I JUST SAW THIS AFTER MONTHS BUT YES ANON I ADORE MAYOLEO SM i need more content of them so bad (including making it myself- *sideeyes the fanfics on ao3 i made*) anyways!! headcanons below

• mayoi learned composing from leo and they make songs together sometimes (mayoi has to stop him from writing on the walls though)

• it takes some time for mayoi to confess because he wants to trust leo but isnt sure if he can. thankfully leo is patient with him and will wait until they're ready. they both confess at the same time

• sometimes leo helps mayoi with his intrusive thoughts because he was in a dark place in his 2nd year so he knows the feeling

• (vigilante au) leo ends up at the places mayoi patrols at (is it on purpose? who knows) and flirts with him. a lot. it leaves mayoi flustered while hes thinking of what to do with this random civilian

• leo rambles to izumi about how he likes this guy whos face he hasnt even seen and izumi is tired ('good for you i guess?' 'I know right?? but like i said-')

• mayoi meets ruka in his civilian disguise!! they get along well :] but once she invites him to hang out with her and her brother to get something to eat its all over for leo

• they both seem familiar to each other but dont notice. once leo hears mayois laughter he falls HARD. ruka teases him for it
