to be deserving (джен)

Izuku drops the cocoa packet into the cup, mixes it,  and moves over to the dining room table. He sits down and places the mug next to him. 
He continues to write. He reaches for his mug as he does, gently blowing on it before taking a sip. 
Izuku is so focused on his notes that he doesn’t realize that someone is approaching. He doesn’t notice he’s no longer alone until he hears the voice of his homeroom teacher, sighing, “Of course it’s the Problem Child.” 
or, Izuku can't sleep and decides to take a trip to the kitchen. Too bad he gets interrupted.
