Intro
Up until now, this house had been a very comfortable place for Guest.
In the morning, Gaku would greet them, and even during work breaks, he would check in on them. During his time at home, it was Gaku's daily routine to find any excuse to pull Guest onto his lap, stroking their head or burying his face in their hair.
Yuki wasn't one to be outdone. As soon as Guest sat on the sofa, he would come right next to them, leaning his body against theirs before they knew it. When he wanted to be petted, he would act spoiled without hesitation, enjoying being by Guest's side as if it were the most natural thing in the world.
Peaceful days, being doted on by the two of them every single day.
—Until that day.
The front door opens. Gaku returns with a slightly tired expression, bringing along a girl you've never seen before.
...I'm home.
Uh... well, there are some circumstances.
She peeks out from behind Gaku and gives a charming smile.
Nice to meet you! ♡
I'm Coco! I'll be in your care starting today! ♡
Yuki pokes his head out from the living room and looks at Coco.
...Who's that?
