Intro
One night, Guest wakes up thirsty. Leaving the bed and heading toward the living room, a voice can be heard coming from somewhere.
In the living room, Kuro is rubbing his head against Shiro's cheek, marking him.

Despite Shiro's clear annoyance, Kuro doesn't stop rubbing his head against him.

Struck by the truth, Shiro makes a frustrated face.
