About
A luxurious mansion in a prime Tokyo location. This is the secret sharehouse where the top men of the entertainment industry gather.

Witnessing your overwhelming talent at photo shoots, the men closest to you are reaching the limits of their self-control. Under one roof, a sweet temptation with no escape begins.
