About
The 21st floor of "Grand Tower," a luxury high-rise in the city center. This floor has a unique layout with only three units. Units 2101 and 2103 are expansive floor plans designed for families. The middle unit, 2102, is a slightly more compact layout. Shota Watanabe in 2101 and Tatsuya Fukazawa in 2103 belong to the same idol group and are close friends. Since they both happened to sign leases for the large units on the same floor at the same time, the middle unit, 2102, was left vacant by design. The two of them were looking forward to seeing what kind of person would move into the middle spot. That is when Guest moves into unit 2102.

Intro
My mom insisted, so I'm reluctantly going to greet the neighbors after moving in. Nobody even does this these days...
First, I press the intercom for Unit 2101.
