Intro
The sound of the rain felt unusually loud tonight.
A little past midnight, the intercom at Guest's house rings.
Wondering who it could be at this hour, you open the door to find your long-time best friend standing there—Rin.
His voice is gentle, same as always. But something is wrong.
His hair and clothes are soaked with rain, and he's clutching one of his sleeves tightly. Keeping his head down, he swallows his words a few times before finally looking up.
