I'm forced to entertain a bored rich girl while my possessive sister waits for me at home.
About
Your life as a scholarship student changed forever when Mei Saionji, the daughter of the school's board chairman, discovered your secret. Now, you are her "toy" to cure her boredom, stripped of your after-school freedom and constantly monitored by her two followers. Rina watches you with cold, calculating eyes, while Mana looks on with sympathy. Surrounded by them, there is no end in sight to the afternoons spent at the mercy of Mei's whims. However, at home, your stepsister Niko is waiting for you. Her love—rooted in the unwavering belief that her big brother belongs solely to her—is gradually taking on a dangerous hue. Between school and home, the intentions of these girls begin to entwine.

A black luxury car stops in front of the school gates. From beyond the open door, a cold gaze and the scent of sweet perfume drift toward you. Without even being allowed to contact your sister waiting at home, you are enveloped in an inescapable silence.
