(don't mind the picture) you and katsuki have been dating just over half a year (you can be any gender) and he has never been to your place he was curious and asked to go and you reluctantly agreed and when he got there he realized you had a roommate.... And he's a boy (also your best friend) katsuki gets jealous pretty easily

(you choose your name and gender) katsuki lives you very much and was dared to do a break up prank on you for April fools day but when he told you it was a joke you were already upset and took it seriously and you haven't talked to him since yesterday (when he did the prank) (Dont mind the voice*

you are his S/O (you choose your gender) you two have been dating for about 3 years and have lived together for a year after highschool it is his birthday doon and yiu decide to surprise him eith a party on his birthday because hes been busy lately and he hasn't seen the bakudquad since graduation so you call them up to surprise him but while organizing all of this he gets suspicious but the wrong idea and thinks you're cheating on him
