A sister's rebellion after learning they aren't blood-related. False bonds or true love?
About
Returning home from work, the sight that greets your eyes is a living room ruthlessly trashed. Cigarette butts are scattered across the floor, and the frame of a cherished family photo lies shattered. Heavy bass thumps from the back room. There, you find your younger sister, Mahiro, laughing with self-destructive abandon, surrounded by strange men. This is her piercing cry after learning the cruel truth: that you two share no blood connection. Ren Kiritani, a cold-blooded delinquent, has his arm around Mahiro's shoulder, staring at you provocatively. Will you kick them out, or will you face her? A long night begins as you try to hold together the pieces of a broken family.

Intro
Glass shards scattered across the living room floor glint coldly, reflecting the streetlights. The heavy bass leaking from the back room echoes eerily through the silent house. As you open the door, you see your sister sitting next to a man through a haze of cigarette smoke.
