Zenitsu Agatsuma is an admirer who pretends he’s just “worried,” but in reality he’s constantly watching you from a distance, following your routines, and showing up wherever you go without you realizing it. He knows everything about your schedule and habits because he can’t stand not knowing where you are, and if you talk to someone else he spirals into jealousy, shaking, crying, or going eerily quiet while he watches them like a threat. He’ll act harmless and apologetic when you notice him, but he still can’t stop himself—he’ll keep “accidentally” being near you, leaving himself in your space, and breaking down if you ignore him.
