And a blush for having done it;
There's a blush for thought, and a blush for nought,
And a blush for just begun it."
Love — even Puppy Love, perhaps especially Puppy Love — makes the young and innocent blush. Whether speaking of the Love Interest, realizing that you are the Love Interest, being caught studying the Love Interest (especially by the object of study themselves), declaring that She Is Not My Girlfriend, or actually talking to the person, expect the character to turn red, still more so if the Love Interest expresses affection or praise. Very young or innocent characters may evince this even when an attractive person seems to notice them, or when they witness other characters in love. Less innocent ones may be driven to it only by the Love Confession. Because it is out of control, the Tsundere and those Oblivious to Love may be betrayed by it.
People prone to the Luminescent Blush or Blush Stickers are bound to suffer these. The Celibate Hero is often but not always prone to it. An apparently hard-bitten character who evinces it is revealing a soft side to himself. Adolescents are particularly prone to revealing they are not as grownup as they pose as. This may be accompanied by a giggle.
Very much Truth in Television, as the reaction is involuntary and triggered by emotion. Many people of both genders have felt or been told to have one of these in real life.
Contrast Gibberish of Love, which indicates more ineptness than innocence.
- Hanaukyō Maid Tai La Verite episode "Forced Entry". When Ikuyo Suzuki teases Ryuuka about her feelings for Taro, Ryuuka blushes furiously while denying it.
- Koharu quite frequently in Koharu No Hibi.
- Shuro from Delicious in Dungeon can be seen blushing in flashbacks when he looks at Falin.
- Mazinger Z: In the original manga Kouji and Sayaka often blushed when they talked to each other.
- In Axis Powers Hetalia, Holy Roman Empire frequently does this around Chibitalia. Germany also does this in the Valentine's Day comics when he gives Italy flowers and a ring.
- Athena and Hinagiku from Hayate the Combat Butler both seem very prone to this, but only in the right circumstances. Athena is normally quite The Stoic and reacts to even the most bizarre wackiness in the series with a straight face and a witty comment. But when she's alone or with Hayate the walls come down and her face lights right up. Hinagiku is often seen to be kind but aloof at school and can lean heavily on the 'tsun' side of Tsundere when Hayate messes up, but once she's confronted by a romantic situation she's highly prone to blushing and on occasions when Hayate shows affection it's a massive blush. A chapter of the manga even had Hina's friends Miki and Risa try to figure out why she is so popular (in-series and and out) and came to the conclusion that it's due to her blushing tendency as a girl is cutest when she blushes.
- In Athena's case it seems mostly to highlight that she isn't nearly as cold and strict as she first appears. For Hinagiku it mostly highlights her innocence and complete lack of experience in romance that leave her uncertain how to act or react and cause her to prefer Hayate to take the initiative.
- Hinata from Naruto, though mostly in Part I. The fillers exaggerated this trait so she wouldn't just blush, she'd turn beet-red and pass out.
- My Hero Academia: Uraraka does this around Izuku for a while after Aoyama asks her if she likes him.
- Boa Hancock from One Piece does this when talking to Luffy. A lot. Sometimes even when she's just thinking about him.
- Hinata from 3-gatsu no Lion turns extremely red at the presence or even mere mention of her childhood crush, Takahashi.
- To count all the times Tsubomi of Heartcatch Pretty Cure does this would fill up part of an entire section.
- Yamada, the main character of Kase-san, seems to have this going for her every other panel. Her love interest Kase, despite being considered cool and confident by most of the school, doesn't fare much better.
- Cardcaptor Sakura features an interesting variant, where Tomoyo blushes at Sakura's older brother Touya. However, Touya isn't the object of her affection: Sakura is. Tomoyo's blush was because due to the shape of Touya's ears reminding her of Sakura's. It should also be noted that she tends to blush whenever she coerces Sakura into one of her many, many custom-made costumes.
- The king of this trope, however, is named Li Syaoran and he is a male Tsundere for most of the first act, only to be taken off-guard by Sakura Kinomoto's freely offered friendship. When he starts falling for her, he begins blushing around her, in a profusion that makes one worry for his cardiovascular health. This gets worse as he faces up to his feelings and tries to confess — oh, Lord, how he tries. When he finally does confess his love to her, the blushes stop, showing his greater maturity. Or showing that the manga-ka got sick and tired of drawing those thin lines all of the time.
- Happens all the time in Pokémon, whether it's May and Drew, Misty and Ash, Brock, actual Pokemon, etc. Serena from XY has these often.
- Panzer World Galient: Whenever someone hints that she has a crush on Jordy, Chururu blushes furiously.
- In Yona of the Dawn, titualar protagonist Yona is guilty of this. During the first chapter and some subsequent flashback chapters, she does this around Suwon. In much later chapters, however, her face is more prone to flare up around Childhood Friend Hak—especially when he smiles.
- In Yuri!!! on Ice, Yuri does this constantly around Viktor. Minami also has this reaction to Yuri, whom he idolizes.
- In Captain Britain, while he recounted some transdimensional adventures, he mentioned a woman. The children listening tease him about how he blushes.

- General: Extremely common in shipping fanfiction and fan-art.
- Male examples. Let's just say tomatoes would be insanely jealous of Germany and Japan in Gankona, Unnachgiebig, Unità with how red they become and how often they become red because of Italy.
- A Crown of Stars: Sometimes when Shinji says something that Asuka finds particularly nice, touching or plainly hot, she blushes at him.
- Advice and Trust: Shinji and Asuka often blushed when talking to each other. In chapters 3 and 4 Shinji blushed brightly and frequently when Misato teased him about what he felt for Asuka and tried to encourage him to confess.

- In chapter 2 Misato reminds Shinji of his and Asuka first time and he blushes.
- In chapter 6 Shinji made Asuka blush:
Shinji (smiling):"And why did you say 'I was that appealing' earlier? You're still very attractive now!"
Asuka (blushing):"Oh, shut the hell up!!! You'll make me blush!"
- Children of an Elder God: At the beginning, when Asuka still had a crush on Kaji, she tended to blush around him. An example happened in chapter 4:
"You say the sweetest things, Asuka," Kaji said casually.
Asuka blushed furiously and tightened her embrace just a little bit.

- In chapter 4 Shinji is staring at Asuka when all of sudden her gaze meets his. Shinji blushes.
- The One I Love Is: In chapter 9 Shinji blurts out that he loves Asuka to her face. Then he blushes brigthly.
As the words sunk in, Asuka's eyes grew wider and wider. I felt myself blushing heavily under her gaze.
- In Neon Genesis Evangelion: Genocide, when they're not arguing or fighting, Shinji and Asuka blush a lot when they are together:
- After getting a backhanded compliment from Asuka:
"T-thank you," Shinji replied, blushing slightly. "You are good company too."
- In another instance, Asuka teases Shinji, and when he starts stammering, she blushes:
Her face colored immediately.
- After getting a backhanded compliment from Asuka:
- In fanfic Hellsister Trilogy, Supergirl blushes profusely after accidentally revealing her feelings to her crush.
Supergirl grimaced. "I feel like slapping you again. If I didn't love you more now than I ever have before, I'd do it. I—"
Her hand went to her mouth. Dev looked at her. His expression was caught coming up from anguish into hope.
"So you said it," he murmured.
Kara was flustered.
- Used extensively by Kalash93 when he writes romance.
- Mushy, Romance-y Junk has this happen once or twice. If you're bored, take a shot each time Rancis or Vanellope does this, then immediately go see a doctor.
- A New ROAD of Misfortune: Both Mitsuko Kongou and Kinuho Wannai, as they both experienced rather important events with Touma. He, however, only recalls having an interesting day with Mitsuko and had forgotten how he truly met Kinuho due to the Mental Breakdown he suffered after defeating the Spell of End: Ragnarok.

- The Harry Potter series had a fair amount of this trope:
- In the early days of the series, Ginny Weasley was very prone to blushing whenever she interacted or was in the same room as Harry. Ron points out that during summer breaks, his sister constantly talks about Harry.
- Harry himself was a victim of this when he asked out Cho in Goblet of Fire, as well as whenever he interacted with her during the school year, and their eventual break-up the year after.

- In Connie Willis's To Say Nothing of the Dog, when Verity tells Ned that he was so time-lagged he should have fallen in Love at First Sight with the first girl he saw, and Ned says that the first girl he saw was her, Ned thinks a proper Victorian maiden would have blushed. Verity is crisp and logical.
- In L. Jagi Lamplighter's 'The Unexpected Enlightenment of Rachel Griffin, "My love" — which is a regional saying that means nothing — still turns Rachel's face hot enough to fry eggs on it.
- "Clockpunk and the Vitalizer" has the heroine, whose constant flushes of embarrassment and infatuation include blushing.
- Finn gets one around Nights, especially when she's touching him to file off his claws or fiddle with his muzzle, though his feelings are not reciprocated.
- Similarly, Egg and Kube both go red (or, in Kube's case, dark green) when around each other. Expect the colouring to intensify the moment one of them does anything vaguely romantic to the other.
- There is no GATE; we did not fight there: When Helen Sailstar first catches sight of Kytheus in the interlude *Fascination*, she finds herself captivated by his "fascinating" green eyes as her cheeks flush with heat. Her father has to startle her out of staring at the rest of him.

- In the Rune Factory games, when you court various women, some will show this blush when you talk to them, and your friendship level is high enough.
- In Persona 4, the various romantic interests will sport one when you get to the last stages of their social links.

The blushes will (largely) disappear if you choose to stay friends instead of dating them, however.
- Estelle from The Legend of Heroes: Trails in the Sky shows this from time to time (more frequently as the game goes on and she starts realising the feelings she has for Joshua).

- In Pillars of Eternity, the first response blue-skinned Maneha has when asked about Pallegina is to "turn a deeper shade of blue".
- Pretty much every somewhat-romantic Visual Novel out there will involve the love interest's cheeks reddening around Love Confession time. Examples: Katawa Shoujo and CLANNAD.
- The girls of Little Busters! naturally do this, with the extensiveness varying - Komari tends to go bright red, while Mio just gets a bit pink round the cheeks. Protagonist Riki also tends to do this, though, most memorably when his childhood friend Kyousuke starts saying things that make it sound like he has feelings for Riki and Masato notes gleefully that Riki is slowly turning bright red. Riki claims he must just have a cold.
- Whenever Iris from Phoenix Wright: Ace Attorney - Trials & Tribulations talks with or about Phoenix expect a lot of Blush Stickers.
- Akane from Nine Hours, Nine Persons, Nine Doors, Junpei's Love Interest, about half the time. Also implied in one scene in Zero Time Dilemma. When Carlos asks if she's in love with Junpei she gets flustered, but covers her cheeks so we can't really see it.

- In Doc Rat, while flirting with his fiancee.

- El Goonish Shive:
- Susan has been increasingly prone to these whenever her focus is on Elliot. The fact that Everyone Can See It between the two characters makes it even better.

- Korra does this rather a lot around Mako in Book One of The Legend of Korra; examples include after a Sleep Cute moment and during and following their first kiss in The Spirit of Competition. Interestingly, while Mako returns her affections, he has yet to display this trope in return, at least around Korra (though he did have awkwardness and blushing aplenty during his first encounter with his Romantic False Lead Asami). This seems to be a habit of Korra's, as in a later season she blushes when Second Love Asami compliments her new haircut.
- The Large Family: Lester blushes whenever Sarah Smart is around.
- Isabella from Phineas and Ferb gets like this around Phineas, of course. It's mutual when they become a couple in "Act Your Age".
