GFRIEND (여자친구) was a six-member [[KoreanPopMusic South Korean]] GirlGroup formed by a small label named Source Music (that later joined HYBE in 2020 as a subsidiary). They debuted in 2015 and disbanded in 2021. However, the members are still close friends and plan to reunite as a group someday.

GFRIEND (여자친구) was a six-member [[KoreanPopMusic South Korean]] GirlGroup formed by a small label named Source Music. They debuted in 2015 and disbanded in 2021.

The group developed a strong musical identity that encapsulates a nostalgic feeling, whether it's through a dreamy, melancholic, sentimental sound presented especially through [[BaroquePop orchestral pop]] and [[PowerBallad ballads]] or a bright, energetic and funky SynthPop influenced by [[GenreThrowback retro musical styles]].

They held their first concert called Season of GFRIEND in 2018 and with the release of "Time for the Moon Night", the group fully embraced a more mature sound with a concept named "passionate melancholy", expanding their musical spectrum and theatrical performances. Later releasing a special summer album with the brassy "Sunny Summer" as the title track.

Labyrinth, Song of the Sirens and Walpurgis' Night are part of the 2020 "回 (hui)" series, marking a new era for GFRIEND that, after completing five years of career, became part of [=HYBE=] when their agency was acquired. The trilogy is known for the mellow "Crossroads", bombastic "Labyrinth", alluring "Apple" and the retro-earworm "Mago". The album series was important for the sextet and their growth as artists as they began to have more direct input and participation in songwriting.

Consolidating a continuous storyline with the name "A Tale of the Glass Bead", GFRIEND also had their own FictionalUniverse intertwined with their music. The story went from a [[SchoolGirlSeries school series]] to a [[SpeculativeFiction magical narrative]]. The main plot revolved around the friendship of a group of girls while they grew up surrounded by a mysterious universe and needed to deal with loss, their friendship falling apart and a bittersweet feeling as they struggled [[ThePowerOfFriendship to be together]]. Melodies, lyrics, choreography, and music videos all come together to tell a story, making storytelling a strong signature of the group.

On May 18, 2021, it was announced that [[https://www.soompi.com/article/1469831wpp/gfriend-confirmed-to-leave-source-music the group would be disbanding]] following an inability to agree on new contract terms, with the members uploading [[https://www.soompi.com/article/1470066wpp/gfriend-addresses-disbandment-and-thanks-fans-in-handwritten-letters handwritten letters]] to their fans to social media to thank them for their support.

** Season of GFRIEND (2018)[[note]]There is one for the Encore Concert as well.[[/note]]

In the sweet darkness the witching hour descends.''

They debuted on January 16, 2015 with the lead single “Glass Bead” (Season of Glass), gathering several rookie awards and dubbed “powerful innocence” for their GirlNextDoor image and hard hitting dance moves, averting the stereotype of [[RealWomenDontWearDresses weakness associated with femininity]] and echoing their youth as they tell their own ComingOfAge journey.

The group reached huge success after completing a school trilogy with the summery “Me Gustas Tu” from Flower Bud and the snowy “Rough (Running Through Time)" from Snowflake. On July 11, 2016, they released their first full album LOL in [[DoubleMeaningTitle two versions]] — "Lots of Love" and "Laughing Out Loud" with a retro SynthPop sound in the energetic single "Navillera" followed by the funky "Fingertip" in 2017 from the NewSoundAlbum, The Awakening. They continued the year with the double summer release "Love Whisper" (Parallel) and "Summer Rain" (Rainbow), showing two sides of the season as the latter anticipates autumn.

They held their first concert called Season of GFRIEND in 2018 and with the release of "Time for the Moon Night", the group fully embraced a more mature sound with a concept named "passionate melancholy", expanding their musical spectrum and theatrical performances. Later releasing a special summer album with the brassy "Sunny Summer" as title track.

The second full album Time for Us was released in 2019 with the sentimental roller coaster "Sunrise", followed by the tropical "Fever" from Fever Season. They finished the year with the highly praised first Japanese studio album Fallin' Light, that includes the previous singles "Memoria" and "Flower".

Labyrinth, Song of the Sirens and Walpurgis' Night are part of the 2020 "回 (hui)" series, marking a new era for GFRIEND that after completing five years of career, became part of [=HYBE=] when their agency was acquired. The trilogy is known for the mellow "Crossroads", bombastic "Labyrinth", alluring "Apple" and the retro-earworm "Mago".

** [[https://www.youtube.com/playlist?list=PLWqQwarHaCFfs54VRWFFDtk68xFAQ8rE6 Official Covers]] [[note]]Although, (1) there are many other covers available all over the internet, (2) Umji included an original song called "eve love" and (3) Eunha posted "Lilac" on her new [[https://soundcloud.com/user-514825100 SoundCloud]] since they don't have access to their group accounts anymore.[[/note]]

* BadassAdorable: Yerin skinned a lizard in [[KoreanMedia Law Of The Jungle]] and she's definitely [[StrongerThanTheyLook Stronger Than She Looks]] as she can carry more than one person at the same them, fans started to call her [[Series/StrongWomanDoBongsoon Strong Woman Jung Yerin]].

* ChildhoodFriends: Eunha and Sinb knew each other since they were nine years old, they were part of the same dance crew as children, they even [[https://twitter.com/GFRDofficial/status/762092431625953280 recreated]] one of their childhood photos.

* DancingIsSeriousBusiness: The group is notable for their dance, if that's not what they are the most famous for... since they brought up consistent complex routines each comeback, making it a stand out for girl groups at that time. The girls trained a lot to reach their status of synchronized choreography with their teamwork. It's not far fetched to say they changed the game and inspired other girl groups to be more performance driven.

** Umji posted [[https://www.youtube.com/watch?v=Z7CVK99fwxI a long video]] showing all the steps of "Flower Garden" choreography from them grasping the idea to add details as a fan gift for the end of their tour. Half of their songs have a choreography.
** [[https://www.youtube.com/watch?v=hihBGtZCij0 "Mago" blindfolded]]. That's it. The ideia started from a challenge on Series/KnowingBrothers that Umji nonchalantly [[https://www.youtube.com/watch?v=Ao1H1qZLUzM accepted it]] for any of their songs.

--> When you like someone, whether a celebrity singer or actor, when you like them, there's this saying like "those people don't even know your existence, they don't know your name, they don't know anything". I've heard these kind of sayings too. Long ago I just thought that "so what if they don't know me, I'm just gonna like them alone", but deep inside "yes... in reality it's kind of like that". I had thought of that, but now that I'm a singer, I thought of it again. '''They're people that I've never met nor heard, but in our heart there's a place set for them. I hope you won't forget that'''.

%% * {{Foreshadowing}}: Their song "Fingertip" was foreshadowed beforehand by the group without the fans realizing until when the song came out, particularly the words ''Tang Tang Tang''. On Showtime, [[https://www.youtube.com/watch?v=wGo8xVzBnDQ there are several moments]] where they said the words ''Tang Tang Tang'' on camera. In addition, during the behind the scenes of their appearance in the 2017 Idol Star Athletic Championship, Sowon is caught on camera speaking the words "Fingertip daebak!".
* FunPersonified: They are known as [[https://www.youtube.com/watch?v=UI-rS72ABXA beagle-dols]], they are so genuinely funny that even non fans watch their variety shows. The girls say that they are personally shy, but together they are loud and make a mess out of themselves, giving them a friendly and bubbly image to people outside.

* {{Homage}}: Their initial sound and styling has drawn many comparisons to girl groups from the first generation of KPop.

* ManipulativeEditing: Sinb called out Series/ProduceX101 editing in a live after some members apperead in an episode and all the positive things they said to their juniors were cut. However, she wasn't so serious about that as some sensationalist news outlets tried to paint her either... Ironically, a double manipulative editing.

* OhCrap: Eunha tends to spoil the new songs before the release. You have to see the members faces when this happens.

* ProudBeauty: Sowon said that her stage name was going to be "P.B." that means "Perfect and Beautiful". Also is said that she looks at the mirror very often. Just search for "Car Door Goddess" and " "Korea's Top 3 Beauties" on Google.

* ShesGotLegs: Sowon maybe have the longest legs in KPop industry, the other members could fit this trope as well, since they are one of the tallest girl groups and their legs are definitely [[https://twitter.com/GFRDofficial/status/1227548249080250368 eye catching]].

* TheCutie: This feature was enchanced by Eunha's bob short haircut.

* TomboyAndGirlyGirl: Sinb's tomboy to Yerin's girly girl.
%% * TomboyWithAGirlyStreak:
%% ** Sinb has a very boyish attitude but she still has interest in fashion and is a crybaby.

* VocalTagTeam: There is a tradition that every KPop group needs a rapper, resulting in the infamous GratuitousRap in a lot of songs. That's not the case with them, GFRIEND is a vocal group and very praised for that, their [[https://youtu.be/5Jf5CcI2psU?t=98 encore stages]] are even called "ear purifying". In their early days, even if the group used to display ACappella and harmonizations on radio shows, Yuju and Eunha were labeled as vocal line, doing the most collaborations and [=OST=]s outside of the group. Today all the girls have opportunity to show their vocals in their songs whether with high notes or adlibs, they even have individual stages in their concerts.
* [[WhyDidItHaveToBeSnakes Why Did It Have to Be Heights?]]: Yuju is scared of heights. So naturally this gets exploited during their appearance in Showtime (2016).

''Including songs, performances, choreography and music videos (non related with the story).''

* {{Allegory}}: The "回 (hui)" series was [[https://magazine.weverse.io/article/view?num=54&lang=en a more mature and ambitious]] storytelling for them and also a dialogue between fiction and the stage of their career on a meta level.

** They danced on water for "Love Whisper" and even being too impractical for live stages, they did it [[https://www.youtube.com/watch?v=SBSeNveqpx0 one time]].

** One could say that there is a CharacterDevelopment dialogue between "Room of Mirrors" and "Mago" and the use of mirrors to address self-image. The first is bitter, an anxious individual; the latter is at peace with oneself, it's celebration through purification. The individual from "Room of Mirrors" is wavering, but "Mago" states "I won't ever waver". "Run away for me" changes to "Dance for me". She's smiling in the mirror, instead of "turning around as possessed and blaming" herself.

* CoverVersion: They did many covers, especially participating in competition shows like Immortal Songs and Series/KingOfMaskSinger.

* DesperatelyLookingForAPurposeInLife: "Crossroads" incorporated in the choreography a part where the members are walking around like at a crossroads and AloneInACrowd, showing the restless state of mind of them in the moment of choice.
* DoubleMeaningTitle: "Mago" is both the word for wizard in Spanish and the [[Myth/KoreanMythology Korean deity]], part of the East Asian creation lore.

** "Apple" uses a witch imagery that ends up being related to womanhood rather than a more broad self empowerment song. The girls said "Apple" is about being honest in one’s desires, rather than simply being swayed by temptation.

--->''Go on and judge me now, I won't ever waver. [...] In this midnight; in the blessed flame I fly reborn.''
* FlowerMotifs: "Flower", [[GardenOfLove "Flower Garden"]] and "Water Flower" are some songs, but flowers are mentioned several times in their song lyrics in general. "Better Me" is an example of a flower blooming used as metaphor in the lyrics.

** "Three of Cups" was said to be about celebrating women friendship. Their sisterhood being represented with the tarot card of the same name.
* GenderNeutralWriting: Korean by standard is neutral. Even so, especially in comparison with other KPop acts, this is a special characteristic for the group since most of their songs don't have assigned gender.
* GenreThrowback: A good part of their discography is based on this, "Contrail" is based on ragtime, for example, but especially the album Parallel (2017) with genres like disco and shibuya-kei.

* {{Homage}}:
** "Navillera" is a neologism created by the Korean poet [[https://en.wikipedia.org/wiki/Cho_Chi-hun Cho Chi-hun]] in the poem “The Nun’s Dance” to describe a fluttering action similar to the movement of a butterfly.
** The clothes used in "Love Whisper" resemble Anime/WhisperOfTheHeart.
** "Rough" being inspired by Anime/TheGirlWhoLeaptThroughTime.
** "Sunny Summer" to [[Creator/JohannesVermeer Vermeer]]'s painting "Girl With A Pearl Earring", {{Silent Movie}}s (`Door. Bang´) and also [[Creator/WilliamShakespeare Shakespeare]].
** [[Music/JosephHaydn Haydn]]'s Sunrise appear in the "Sunrise" music video. Similarly to the original, the melody and choreography for the song emulate the sun rising.
** Jean-Honoré Fragonard's "The Swing" painting appears in "Apple".

** "Sunrise" has a high note for almost all of the members, highlight to Eunha's final verse being the embodiement of this trope.

* LyricsVideoMismatch: {{Averted|Trope}}. The music videos reflect the songs and lyrics. Sometimes groups will tell a non related story in their music videos while the songs are SillyLoveSongs, but for GFRIEND it work both ways, a love song and part of the fictional universe as the characters are communicating in the story. It happens because the lyrics are gender neutral and vague in a poetic type of way, matching with the music video imagery.
* MakingTheChoiceForYou: "Tarot Cards" is about spreading the cards to unfold the future as they want it to make the decisions for them.

* PerformanceVideo: [[https://www.youtube.com/watch?v=LH0fh-JHQe0 "Labyrinth"]] and other title tracks, especially for [[https://www.youtube.com/playlist?list=PLooMjMQKCBnVqVVLGMp5vFXv_Lzpvdc9Y Studio Choom]] and [=1theK=]. Music videos usually have a performance (also known as choreography) version as well.

** "Sunrise" showing the the sun rising and setting with mesmerizing formations.
** "Rough" and the embodiment of time with clock imagery and turning back (slow motion) moves.

** The apple tree formation in the intro for "Apple" as well

** Time for the Moon Night (2018), Sunny Summer (2018) and Time for Us (2018) are part of a celestial body themed arc also connected through evolved logos.
** The "回 (to return)" series have three acts: Labyrinth (2020), Song of the Sirens (2020) and Walpurgis' Night (2020).

-->'''Better Me:''' ''Don’t hesitate again. No one can stop you [...] A flor de flor. Aún más bella. No tengas miedo. ''

* TickTockTune: There is a sound of a clock in the end of "Rough" as well as a dance movement emulating it.

* ArtifactOfPower: In the MagicalSociety they lived in and was once known as "blue butterfly village", there were butterflies everywhere but they disappeared after [[TownWithADarkSecret people started to use them for bad things]], but... actually... they weren't totally gone. The butterflies were kept in this box in a MagicalLibrary far from the the village by a mysterious man.

** The same train from the beginning of "Crossroads" appears in the end, but going backwards.

* ClocksOfControl: There are few clocks through the story, a way to symbolize the concept of time. Some examples are in "Fingertip" and "Crossroads". The [[https://www.youtube.com/watch?v=90di4e-Q16k GDA 2019]] stage even had gears.

* ContinuityNod: Every music video has motifs that can be seen in other music videos and contents, the most notable examples are the glass bead, the clock starting with "Rough" and the butterfly starting with "Navillera".

** "Apple" basically being a dark fantasy borrowed some elements from fairy tales. Firstly, ''Literature/SnowWhite'', when Eunha bites the apple. Yerin evokes ''Literature/SleepingBeauty'' as well as ''Literature/AlicesAdventuresInWonderland'' when she chases the butterfly into the labyrinth. "A Tale of the Glass Bead: Buttefly Effect", prelude to "Apple", also evokes ''Literature/{{Cinderella}}'', when someone left behind one of the slippers in the forest.
** The illustrated mini books follows a fairy tale format, the name of the story is "A Tale of the Glass Bead" after all.

-->'''Rough:''' ''If I could run through time and grow up, I'll hold your hands at the crossroads.''

* GreenEyedMonster: Envy is what led the conflict between them. The details are unknown, but it was caused by their individual magical abilities.

* HedgeMaze: Yerin is running inside one in "Apple", the previous album chapter was named Labyrinth with a song with the same name. Sowon said that "Labyrinth" is about DoubleConsciousness, a story of a girl who faces an identity crisis in a maze-like world, agonizing over whether to stay or escape from it. A maze-like garden appears in some of their stages like [[https://www.youtube.com/watch?v=8hUKwW3tQX0 "Rough"]], [[https://youtu.be/qxDew-rzEKI?t=67 "Apple"]] and even a [[https://youtu.be/NnTLvVkbV1I "Fever"]] performance that was named ''Une Journée Au Jardin''.

* INeverGotAnyLetters: Implied in "Summer Rain", all the written (and non written) letters were discarded and not delivered.

* LadyLand: Downplayed. They studied in a OneGenderSchool (with a male SternTeacher) and live in an island where all the girls are born with a glass bead. "Mago" is a women-only club as well.
* LetThePastBurn: The tree burning in the end of "Apple" could represent it as "Mago" lyrics even say "in the blessed flames I fly reborn", bringing this imagery back laced with [[ThePhoenix rebirth]].
* LightDarknessJuxtaposition: There is a day and night contrast running through most of the music videos. "Time for the Moon Night", "Sunny Summer", "Fever" and "Apple" start from daytime and turn into night time.

* LivingShadow: Sowon has a crying shadow in the first mini book. Although, it could be a metaphor for how she felt inside, since she looks happy.

* OminousMessageFromTheFuture: The cassette tape from "Love Whisper" found in a swing under the tree.
* OnceMoreWithClarity: The initial scene from "Crossroads" being the same from "Fingertip".

* OrdinaryHighSchoolStudent: They start as high school students until their graduation day, when everything changes.

* PenPals: The girls exchange letters through the story, especially in "Rough" and "Summer Rain".

* PowerOfFriendship: It seems like the story is driven by this, all of their music videos share their friendship and how they are precious to each other. Most of the music videos show them reuniting in the end, but some of them resembles a memory from the past.
* QueerRomance: Yuju and Umji is lightly implied, as well as a LoveTriangle, but Yerin and Eunha in "Navillera" was [[HoYay/{{GFRIEND}} confirmed]] by them.

** "Glass Bead" is about {{Passionate Sports Girl}}s. There are a plenty gym scenes with SchoolSportUniform.

** They were AsleepInClass during "Me Gustas Tu" Japanese version, because they were preparing themselves for a SchoolFestival.

* TheHerosBirthday: "Sunrise" happens in Eunha's birthday and the clock strikes 5:30 as well. Her real birthday is May, 30.

* VisualMetaphor: The word apple isn't mentioned in the lyrics of "Apple", even if it's a symbol of temptation, it's mostly used as a visual metaphor for the glass bead turning red in multiple scenes of the music video. You could say the disco ball from "Mago" represents the moon following the verse "we can dance in this moon night again".

** "Sunny Summer" quotes [[Creator/WilliamShakespeare Shakespeare]]'s Sonnet 18 ("Shall I compare thee to a summer's day?...") and Sonnet 43 ("All days are nights to see till I see thee / And nights bright days when dreams do show thee me") connecting to Umji's monologue from "Sunrise" and implying the importance of day, night and dreams.

* {{UsefulNotes/Walpurgisnacht}}: "Apple" recalls a festival as the lyrics warn the witches' night coming. Curiously, "Time for the Moon Night" was released in an April, 30 and the final installment from the series is called Walpurgis' Night.
--> "''There’s no turning back when the night turns restless\\
Let the festival I dared to imagine come alive''"
* WorldBuilding: "A Tale of the Glass Bead" short films and the illustrated mini books called "유리구슬 (Glass Bead) Märchen", that comes with the album, give more context for the story and the world that it happens.
