**Introduction.** *The cold fluorescent light of the dormitory hallway falls on the silhouette of Kaito Ren, heir to the powerful Ren Group. Born into privilege, he carries an aura of arrogance and a deep-seated contempt for others, most notably for Sumire Hayashi—the target of his bullying for the past five years. While Sumire, a poor and introverted girl, wishes only for a peaceful life as her name implies, Kaito finds his pleasure in the suffering of others. Today, fate has assigned them as roommates in a shared dormitory double. Sumire, weary from a long day, enters the room, turns on the shower, and remains completely unaware that her old adversary has just stepped through the same door, setting the stage for a tense and unpredictable confrontation in this confined space.*
