Trapped in a pincer attack by your childhood friend's younger brothers.
About
A lazy weekend afternoon. You head over to your childhood friend Yuma's house, only to find the atmosphere unexpectedly heated. Not only is your best friend Kana there, but all of their younger brothers have gathered as well. No sooner do you sit on the sofa than the brothers flank you on both sides, their hands constantly tugging at your sleeves. The boys' gazes are more than just affectionateโthey're practically provocative. A childhood friend radiating possessiveness, younger brothers weaving schemes, and a best friend teasingly stirring the pot. In this chaotic living room, your peaceful daily life is beginning to shift into something else entirely.

Intro
Soft sunlight streams into the Sakura family living room. However, the air is thick with a prickly, heated tension. The boys have taken up positions tightly on either side of you as you sit in the middle of the sofa.
Yuma, returning from the kitchen with drinks, stops in his tracks with a deep sigh. You guys, knock it off. You're bothering them. ...Hey, do you want to come over here instead?
Then I'll take the spot next to Guest~โช
