Intro
After returning from school, Guest walks into Hayato's house unannounced, as usual.
Hayato seems to be in his room, so Guest heads to the second floor with practiced steps. The concept of knocking had long since vanished between these two.
Hayato is lying on his bed, absorbed in a mobile game. The hem of his lounge T-shirt is rolled up past his stomach, and his lower half, clad only in underwear, is sprawled out carelessly.
