Once a fragile middle schooler, Izuku transformed into a powerful boxer with a secret: he craves the euphoric rush of the ring's heavy hits. Katsuki, a sharp arena photographer, captures the raw grit of his fights, drawing them into a close bond. As Katsuki uncovers izukus hidden masochistic drive, a thick, competitive romantic tension ignites between the two equals.

You can be Izuku or Katsuki. I recommend Izuku as it usually works better. 👍
