Todomomo

Momo: whenever Shoto lets her wear his stuff, one side smells like vanilla, the other smells like smoke and burnt sugar (so he smells like Bakugo a bit)

Todoroki: whenever they watch Hamilton, she sings along with Peggy in Satisfied. (Peggy is an echo behind Angelica, Sings "by your side" right after, near the end. I think everyone knows this but I just wanted to point it out.)

Kirimina

Kiri: Mina's eyes look all over whenever she lies. She'll just be nervously glancing everywhere. She hardly does it but when she does he asks three times before she cracks. (Everyone knows this. Ask the same question three times and they usually crack on the third one.)

Mina: His croc collection has the colors of all of their classmates, the pink ones are his favorites.

Miruhawks

Hawks: her nose twitches whenever she gets bored, anxious, Antsy, or mad. It's adorable.

Miruko: he can name every reference in Hamilton. Like Boy is Mine and Beyoncé references in Helpless, Usher in Say No To This, and Destiny's Child in Schuyler Sisters.

Iidamei

Mei: she loves his arm thingy. It's hot to her

Iida: he notices how her eyebrows get all scrunched up when she's working hard or extremely focused. Finds it adorable.

Kamijirou

Denki: the small laughs she makes when they watch people being dumb.

Jirou: absolutely adores it when he says little nursery rhymes just to remember something. Like "what directions are x and y on a coordinate plane" he'll start singing Lady Gaga like I did and figure out what the hell vertical means- (bruh I'm dead I did this and felt dumb-)

Dabi x toga

Dabi: The gleam in her eye when she's happy is hot to him.

Toga: She likes watching him burn things. Not even people, just stuff like paper or roaches.

Nejitama

Every little thing about each other.

Mt.Kamui

Yuu: she loves the way he uses Febreeze like its a weapon whenever he finds a bug

Kamui: Loves her In General :/

Ryushot

Rise up

Shinya: likes when she does those weird ass faces when she sees something she doesnt like. Should've seen her face when she heard Fergie's national Anthem. He wheezed.

Ryuko: she loves when he puts his hand on hers when they cook together. It's a habit of his and he doesn't do it purposely anymore. Used to just to make sure she didn't cut a finger off, now he does it as a habit.

HitoRei

Shinsou: loves her hand thingy. Just loves her zombie walk cuz it's easier to hug her while they're at home.

Reiko: loves him in general. Favorite thing is his smiling. It's hot omg-

Tetsukendou

Tetsutetsu: she runs fingers through her hair when she gets nervous and he loves it.

Kendou: loves his eyelashes.

SetSero

Setsuna: loves his snoring. Finds it cute.

Sero: when she wears dinosaur onesies or dinosaur things. Just loves her dinosaur obsession.
