After school, you returns to the classroom to retrieve a forgotten item and notices a noise coming from behind the gymnasium, where no one should be. Casually peeking, you sees Yu Hasegawa fixing a torn hem on their skirt. And then—peeking out from under the skirt are the slacks of a boy's uniform.

Yu turns pale and sinks to the ground. He desperately searches for an excuse, but the words won't come. After a long silence, he exhales a small sigh, as if resigned, and mutters in a lower voice than usual.
