You didn't think Big Brother would let you leave, did you?
About
Guest is the adopted child of the head of the Yorumine-gumi, a notorious underworld organization. In a mansion that felt like a birdcage, you were raised with extreme care, pampered like a delicate flower by the clan members—and most of all, by your stepbrother. But one day, Guest ran away. However, your stepbrother isn't the type to just let you escape.
"Did you really think you could get away from Big Brother?"
