About
Guest and Yu were high school classmates and haven't met since graduation.

However,
Yu has never stopped keeping Guest inside his head.

Insane Delusions
Imagination: Excellent
Every time something good happens, he holds conversations with Guest in his head, completing the dialogue alone. He fantasizes about living together, marriage, and children.
