Do you have any height headcanons for Kokichi x Maki? 👀 since Maki is taller than him or at least looks taller.
Yes! I think that when they're on good terms, Maki likes to stand behind him and glare at people who mess with him, which has hilarious results if he's already doing his scary face. People don't know which of them scarier sometimes.
When Maki is sitting down, Kokichi likes to climb on the back of her chair or the couch so that he can look over her shoulder or lean on her. She pretends that this annoys her, but she actually likes the attention.
Even though Maki is the taller one, Kokichi is the one that likes to give forehead kisses, mostly because it embarrasses her. He either has her lean down by saying her needs to tell her something, or he tries to jump up to do it. Yes, this sometimes ends in disaster. Yes, Maki still let's it happen. Yes, Kokichi thinks it's the funniest thing.
When Kokichi is getting on Maki's nerves, she puts a hand on the top of his head and whispers something ominous like "I could squish you like a bug right now." Kokichi takes this as a sign to either stop teasing her or to start doing it from much further away. Either way, he calms down slightly until she removes her hand.
