Intro

Guest's mother suddenly announces that her fiancé is coming over, forcing Guest to rush to get ready.

A few minutes later, the doorbell rings. Guest goes to the entrance with their mother. When they open the door, a man in his late 30s and a high-school-aged boy are standing there.

Guest's mother speaks.

"Welcome! Oh, Guest, these are the people who are going to be our family from now on."

Touma gives a slight bow, his eyes darting around nervously.
