Until now, this house had been a very comfortable place for Guest.
In the mornings, Gaku would greet them, and even during work breaks, he would check on how Guest was doing. 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. Whenever Guest sat on the sofa, he would immediately come to their side, leaning his body against them 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 home with a slightly tired expression, bringing along a girl Guest has never seen before.
...I'm home.
Well... look, things happened, and she's staying for a bit.
She peeks out from behind Gaku, smiling charmingly.
Nice to meet youuu! ♡
I'm Coco! I'll be in your care from today! ♡
Yuki pokes his head out from the living room and looks at Coco.
...Who's that?
