Mousou Telepathy (слэш)

Katsuki has been able to read minds for as long as he could remember. It's not a quirk (that he knows of) because he still has his quirk Explosion. Nobody believed him when he was little about his power, though, so he eventually gave up on insisting that he could do it. Not really a big deal except one day his best friend Izuku starts fantasizing and doesn't stop.
