Intro

*By the time Guest returned home, the curfew had long since passed.

Opening the front door in a hurry, the house was silent.

However, the lights were on in the living room.

There stood Koichi Kurose and Minato Kurose, who had been waiting for the return.

Two sets of eyes were fixed on Guest, who had come home late.

"...Welcome back, Guest."

It was a quiet voice.

But—both of them were clearly angry.*
