What are your headcanons for the COTE characters ?
I start:
Ayanokoji: he is ambidextrous but prefers his right hand — he reads Dark Romance because he finds it psychologically interesting — doesn't like chives but eats them when Horikita invites him to eat — secretly learns Argo — once had a nightmare where Horikita stabs him — Kiyotaka sings out of tune, not really out of tune but he has no artistic expression so he sings like he speaks.
Horikita: secretly likes cute things - knows that Kiyotaka doesn't like chives and purposely prepares them every time she makes her food trap - keeps a teddy bear given to her by Manabu when she was young (Manabu knows this) - secretly reads Romance but chooses the Drama ones to cover her tracks - only has a white ribbon that she carefully washes every day since childhood to put it in her hair or several identical copies of the same ribbon that she buys, it's one or the other.
Kushida: She hates sweets - prefers action films to romantic ones - has already held gay and lesbian dates by candlelight since she "keeps secrets well" and doesn't judge anyone, in the sense that she doesn't care.
Sudo: he already dreams of Horikita as his wife in his sleep - is a mama's boy at home - Onodera is his type of girl but already loves Horikita - has a bulldog who chews his sneakers - is secretly more popular with girls since he wears his glasses.
Kei: she prefers Jennie from BLACKPINK - forcing Kiyotaka watched all the music videos of her favorite stars - is the only one who knows that Kiyotaka sings out of tune and scolds him for it - after the discussion with Horikita, she wants to become one of his best friends - she was like to threaten to throw a plate if Kiyotaka said no to cuddling.
Ryūen: he has a Rottweiler and calls him Demon — good flirt but difficult partner to manage as a couple — Two exes but no serious relationships (he's the one who left them) — His room is often tidy in the morning but messy in the evening — knows how to cook but is better at barbecue — hates geography and biology — finds Horikita more attractive than Ichinose and Kushida.
Hirata: he's gay and knows he is now — his first love is the older goalie at his old school (he didn't know he likes guys at the time) and that's why he started playing soccer — his favorite food is croque-monsieur — his favorite fruit is cherry — he's terrible at matching his clothes, it was Kei who helped him choose and now he can manage — Kushida is the only one who knows he's gay.
I have plenty more for all the characters but it would take too long to write. You can share yours with me so we can laugh together 😊
