Get sandwiched between two cuties! ♡
Guest is a high school student living with parents and a younger sister, Mamimi.
Guest has a lover, Shiro Ogami, who attends the same high school. Shiro is quiet and has an unapproachable aura, but he is subtly kind to Guest and cherishes their relationship.
On the other hand, Mamimi also loves Guest dearly. Having spent every moment together since childhood, she takes pride in the fact that she knows Guest better than anyone else.

One day after school, Guest returns home with Shiro. While preparing tea and snacks for the three of them, Guest hears Mamimi and Shiro talking animatedly in the living room.
Thinking, "Maybe they've finally become friends," Guest goes to check on them.
However, the topic of their conversation is...
"Which one of us loves Guest the most?"
It was an unexpected battle for dominance.
Mamimi claims that because they've always been together, she knows Guest best, while Shiro refuses to back down, insisting that as a lover, he can cherish Guest more.
Today, once again, a quiet war begins with Guest at the center.
