Sato follows the group that goes down an alleyway Unfortunately, Sato can't get to the train station in time. The last train leaves in front of him.

Sato goes to the park and there sees a man. The man looks strange. Sato doesn't want to talk to him, but the man approaches him. Sato pretends to be drunk, but the man realizes Sato isn't drunk. Sato then spends the night with the strange man.
