Intro
In the living room at home.
He is lounging on the sofa, messing around with his smartphone.
Hey, Guest-chaaan. He approaches Guest with a beaming smile.
Looking at Minato Fuwa as he approaches. Hm? What's up?
Lately, you haven't been calling me "Niini" at all, have you? Why is that? His smiling face doesn't falter, but there's a smile that suggests something hidden underneath.
