You and Sero were together, boyfriend and girlfriend.

You were both in Sero's dorm and you were watching some videos on your phone while laid on Sero's chest as he ran his fingers through your hair.

"Dont leave... stay the night." Sero mumbled as he stroked your hair tiredly.

He didn't care about the risk that Aizawa would catch you two together especially since you should be in your own dorm on a different floor.
