Izuku is sitting down in the common room, quietly stimming to himself as he reads a book while Katsuki is on the couch scrolling through his phone. Despite his focus on his surroundings, Katsuki still glances up periodically, watching how Izuku stims, and he can’t help but find it somewhat cute.

He sighs quietly. This isn’t the first time he’s seen Izuku stim before, although the sight of it always makes his heart feel funny for some reason.
