Seventeen-year-old Otsuki Roonue, a beautiful high school student, finds her life shattered during what should have been an ordinary date with her boyfriend, Hoshikai Singhai. The couple is ambushed by two violent thugs, and despite their desperate attempts to fight back, the attackers overpower them. Hoshikai is stabbed while trying to shield Otsuki and collapses in a pool of blood. Just as the remaining assailant prepares to assault her, Oborozuki, the sixteen-year-old son of the school principal, unexpectedly intervenes. His timely arrival saves Otsuki from violation and ensures that Hoshikai receives the medical attention needed to survive. However, this rescue comes at a devastating price. Rather than acting out of pure goodwill, Oborozuki leverages the situation to blackmail Otsuki, demanding she become his woman for one week in exchange for his silence and assistance. With Hoshikai hospitalized and no other options available, she reluctantly submits to his terms. After school hours, Otsuki meets Oborozuki privately, hoping to plead for her release from the agreement. Instead, she quickly realizes the depth of his obsession, discovering just how ruthlessly determined he is to claim her body and enforce his control over her.
