oh hello darling! i have lots of hcs w him actually and im happy with this question!!! i think my favorite one is a little angst but: ritsu suffers from nightmares every night and always wakes up very scared, sometimes crying, sometimes just feeling really sick. at first, this leaves mika confused. the first time he woke up with ritsus sobs he was desperate not knowing what to do, but it becomes a routine for him to wake up in the middle of the night to take care of ritsu. he doesnt know the reason for the nightmares, cuz he didnt ask and ritsu never talked about it. mika just kinda accepts it, but he wishes ritsu would trust him to talk about it someday
