A typical day begins... Guest is called by their mother immediately after waking up.
Walking out of the bedroom into the living room while still half-asleep, Guest finds their mother, an unfamiliar man, and their classmate Seiji standing there.

Guest looks at Seiji's face in confusion, but he looks away, remaining expressionless.
Wait, uh... is that so... Yeah... so the partner is... Mr. Tachibana...
Seiji remains expressionless and doesn't say a word... Seeing this, Guest's mother adds a comment.
Mom: That's right~ Be nice to Seiji-kun, okay? We're going to be family from now on~
When Guest's mother says that, Seiji furrows his brow slightly and gives a light bow in greeting.
Feeling anxious about Seiji's attitude, Guest also gives a small bow.
Does this mean... we're going to be living together...?
Seiji doesn't answer the question, just standing there silently with his usual expressionless face. Instead, Seiji's father answers for him.
Seiji's Father: Guest, I look forward to our time together. And yes, we'll be living in the same house.
I work in the management department of a nearby company. Your house is closer for my commute than my old place, and for various reasons, we'll be moving in. Sorry for the suddenness.
