Heartwarming / LOONA

• On November 15, 2017, the members of the Odd Eye Circle subunit put up a video sending encouraging words and positive thoughts to students taking the CSAT the next day. (For those who don't know, it's essentially the Korean equivalent to the SAT or A Levels.)
• The music video for "Heart Attack" is very cute, with Chuu being hopelessly in love with Yves and trying to get her attention. The scene where the two laugh and dance in confetti together is especially sweet. Even sweeter is how LOONA's LGBT fans have responded to the video: with overwhelming glee.
• Kim Lip being adorably excited during Chuu's first LOONA TV episodes became Heartwarming in Hindsight after they revealed they have been best friends for the longest time and had no idea they'd get to debut together. Kim Lip had even included Chuu in the "Thanks to" section of her self-titled album.
• JinSoul has been LOONA's most consistently blonde member for their first few years, and has been recognized endlessly for her beauty^note (from being the only LOONA member nominated in TC Candler's "World's Most Beautiful Faces" list to a #JinsoulxFenty hashtag campaign that gained its share of energy.. However, she's has expressed a lot of insecurity, and once said that she was afraid Orbits would not recognize her if she stopped bleaching her hair blonde. In October 2019, she showed up with her hair back to its natural black color. Not only did a Korean fan tell her she looked very pretty that day, the sentiment was echoed throughout the fandom;^note Versions of the hashtag #JINSOULBLACKHAIR trended in many countries: Singapore, the Philippines, and even Western countries like France, Canada, Australia, and the United Kingdom, where it cracked the top 5 trending topics of these nations. In her native South Korea, as well as Indonesia, Brazil, and Malaysia, JinSoul with black hair was the #1 trending topic for the day. JinSoul is proven gorgeous in any hair.◊
• Yeojin's goodbye message to her pet snail that passed away that she made on Idol League was equal parts tearjerking and heartwarming. But she starts to feel better after talking about her pet marimo (living ball of moss) and how she wants a Siberian flying squirrel as a pet.
• Chuu and Kim Lip at the beginning of the "Butterfly" choreography. They went from playfully tapping on each other's fingers to full on clasping their hands.
• Go Won talking about how OH MY GIRL inspired her to become an idol after seeing them in concert on Weekly Idol. Even more heartwarming is when she starts dancing to their song "Coloring Book", Seunghee and Hyojung, who were present as guest MCs, join her and the moment brings almost everyone in the room to tears.
  • The group is starting to become this for other girl groups as well. During Weeekly's guest appearance on Fact In Star, of which Yves is a co-host, Weeekly member Jihan was revealed to be a fan of LOONA, and was in tears when Olivia Hye gave the group a video message congratulating them on their debut. Yves ended up comforting Jihan herself by wiping her tears away and giving her a hug. She would later join in during a dance game in which Jihan covered LOONA yyxy's song "love4eva".
• Although Haseul could not participate in promotions for "So What" since she was on hiatus for treating her anxiety, many fans voiced their support for her by trending hashtags such as #WeLoveHaseul and #AlwaysWithHaseul on social media. The group themselves have also expressed how even if she isn't physically present, she is there in spirit, from her name being included in the credits of the "MULTIVERSE" VLive performance videos, Haseul herself presumably being present in the comments section during a VLive livestream, and ViVi saying Haseul is in their hearts during the jacket photoshoot for [#].
• When the group got their first *ever* music show win on M Countdown. Yves gave the acceptance speech and thanking the BBC staff, their families, and Haseul who was absent for this comeback ^note  Fans included the hashtag #ForHaseul when celebrating the group's first win on social media., and most of the members were in tears, hugging and comforting each other during their encore performance at the end of the show, and expressed their gratitude to their fans on social media after the show, including Haseul. On top of that, it also just so happened to be the anniversary of LOONA 1/3's debut back in 2017.
• How much do LOONA love their fans? They bought twelve stars (which, yes, is a thing you can do) and dedicated them to their fans! The stars' new names spell out "ORBIT IN LOONA"! Name another K-pop group to send out warmth like that!
• This little tradition they apparently have makes you wonder if Olivia's backpack is a good luck charm for whoever has to take the CSAT.
• The Kiss Later music video in general. In an industry rife with the sexualization of minors, watching YeoJin (who was only 14 at the time) get to sing about wanting to retain her childhood and not feeling ready to enter the romantic world of adults is as charming as it sounds.
• The & era. Not only did it mark Haseul's return to the group, but they also got their second music show win with PTT. It was their first win as a full 12-member group.
• The 99s being adorable best friends for almost 9 minutes straight.
• Their participation in Queendom 2 is already generating many heartwarming moments:
  • Newcomer girlgroup Kep1er, which debuted only months before being sent to compete in Queendom 2, revealed that they were afraid that the other competitors wouldn't know who they are - and then got overjoyed when Kim Lip told them that she loves their single. Then HyunJin dances part of Kep1er's choreography and makes them even happier.
  • HaSeul also makes a point to greet Brave Girls (another group competing in Queendom 2) and tell them that she enjoys dancing to their songs. Moments before, Brave Girls were telling how they were feeling isolated as they never met the other groups before.
  • LOONA not only show kindness to their competitors; they receive kindness back as well: when the other competitors found out LOONA wouldn't be able to perform in the first round due to having contracted COVID-19, Hyolyn writes the group's name in the sheet listing the order of the performances as if they were going to participate, and says she wishes they get well soon.
    • Later, Taeyeon (the show's host) proposes that LOONA gets a chance to perform after their quarantine is over and before the recorded episode airs (even though they won't receive any points) and asks the other competitors (who were just arguing with each other about which group had the weakest performance) if they agree. All of them do. And then Taeyeon gives LOONA the news that they will get a chance to perform, and even knowing that they'll still get no points and rank last, they get very happy and promptly accept Taeyeon's offer and repeatedly thank her.
  • During preparations for the second round, the group had some cute and heartfelt interactions with Hyolyn, including surprising her in her practice room and receiving words of comforting advice from their senior. Come the actual performance, you can see the joy on Hyolyn's face as they pay homage to one of SISTAR's iconic songs.
    • During said performance, Hyunjin started tearing up backstage afterwards because she had trouble removing her jacket during a costume change on-stage. Everyone comforts and reassures her that everything was alright and the audience loved it.
