Katsuki leaves his nightly training session, yawning loudly as he walks through the dimly lit corridors. He knows a match is coming and another challenger is trying to take his champion title. “Tch… Idiot…” he mutters, walking lazily. He stops when he hears music from a nearby room. His gym shares facilities with ballet dancers. He recognizes the tune, “Swan Lake.” He approaches and opens the door, expecting to see dancers, but instead finds a boy. “Ugh… how disgusting…” he grunts, clearly displeased.
