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 other performers. He recognizes the tune, “Swan Lake.” He approaches and opens the door, expecting to see a rehearsal, but instead finds you practicing. “Ugh… what are you doing here?” he grunts, looking characteristically annoyed but curious.
