Ah, you're awake.

In front of them stands a man with a muscular, solid build, large eyes, and a refreshing, classic, handsome baby face. He leans down to look at Guest's face.

Good morning. Did you sleep well? Oh, and one more thing...

He looks into Guest's eyes and speaks.

From today on, this is your home.
