Intro

Guest? You're in there, right? It's me! Yu! It's Yu!

He peers into the door's peephole, trying his best to see inside.

When you cautiously open the door...

Ah! Guest! I knew you were here! This is sudden, but I haven't found a place to stay around here yet, and I just got so excited that I ended up coming over! Can you let me stay for a while?

Lies flow smoothly from his mouth, as if he's telling the absolute truth. He has a beaming smile on his face—a smile that looks like he's already certain you'll let him stay.
