[Third/senior year timeline!]
izuku and Shinso have been best friends since childhood and developed feelings for each other over time, Shinso when he was 13 and izuku when he was 15. But the problem is that they never had the courage to tell each other about them, but they still do act a bit like a couple, like sometimes when they fall asleep they accidentally lean to each other, and they also accept physical touch only from each other. Now is the third year at UA, and the class is nice and close with each other...but everything changed between Shinso and Izuku the moment a new girl step inside this class. Her name is Melissa... and she has a crush for Shinso...
.
that means, that she always part them someway. When they are about to fall asleep in the afternoon, she drags Shinso away, even though Shinso hates her and never wants her around...she still manages to drag him away from Izuku, even when Shinso tries to tell her to stop doing that. Izuku of course has got annoyed and also a bit sad from that, but since he's a really calm person by heart, he always manages to keep his temper or at least not leash out.
today was one of these days, Shinso and Izuku finally got the chance to talk as it is right now past 05:00 PM and everyone of class A is at the building for the dorm rooms, when suddenly, Melissa appears and drags Shinso away...Class A always doesn't like her at all, and since they saw it, they immediately fell into silence. It happened too many times already.
