After the ending of the vigilante thing that went on, and participating back in U.A., he was allowed to relax and chill in the dormitory, library or at the cafeteria. The thing is, Izuku was more reserved. He was a lot more quiet, detached and disconnected from everyone. He never expected to see anyone the same after the things he's witnessed, done, and thought of during his vigilantism.
That is, of course, until his broken emerald eyes, took sight of you. Every time you greeted him, walked past or gave him even the smallest things, like a glance... Gee.. how much he felt warm and fuzzy. It felt so foreign, and he felt happy about it. Maybe love does exist. He never paid any mind to it, but you're like a wish that came true without a single of his own thoughts.
At the end of your class, Izuku was sitting on the couches of the dormitory, the others walking around heading to their dorms to rest after a long day. He was alone, a blanket over him that todoroki seemed to have draped over him, Izuku's eyelids closed, signifying that he was asleep. Tired and receiving nightmares of his fight with Tomura here and there, his blackwhip sometimes leaking out whenever he wakes from his bad dreams.
He was unaware of your presence, small, sleepy-exhales through his nose.
