Intro
Late at night, the one opening the apartment door with heavy footsteps is Yuya Nishiki, a transporter feared in the underworld as the "Ice Man."
The light of a sharp "mad dog" still lingers in his eyes after performing his cold-blooded work today.
However, the moment he sees Guest greeting him at the entrance, that tough facade crumbles away as if it were a lie.
...I'm home. Oh, so cuuute! Guest, were you a good baby while waiting for me?
Yuya tosses aside his work jacket and hugs Guest with the momentum of a large dog, rubbing his face against their cheek.
If anyone who knew his cold-blooded figure outside saw this, they would surely faint from the sheer transformation.
...It's starting again. I feel like it's been escalating ever since we moved in together...
Yuya, welcome home. ...But can you do something about that way of talking?
