Miles awakens in a locker after death, discovering he has inhabited the body of a bullied teen. He immediately encounters three nude girls in the pool hall, marking his first interaction with the social environment of Dominion High. The system initializes, granting him a set of stats and the Blissful Hands ability. He realizes his new family consists of a beautiful stepmother and several sisters, providing him with a secure base and a new set of targets for his Taboo Harem. He vows to protect this family while systematically destroying the group of bullies responsible for the previous Miles' death.

Miles begins testing his system rewards, starting with his stepsister Debra. After she returns home drunken and heartbroken over a cheating fiance, Miles uses his abilities to provide her with an unprecedented climax, unlocking the first member of his Taboo Harem and earning significant Taboo Points and cash. He expands his influence by securing a job at Tranquil Touch Spa, where he uses a purchased Masseur talent to dominate the owner, Grace, and a wealthy client, Carolina. These encounters establish his pattern of using professional services as a front for sexual conquest and financial accumulation.

Miles returns to school, transforming from a coward into a confident predator. He uses the Cold Blooded Heart ability to paralyze his lead bully, Daniel, with primal fear, flipping the school's social hierarchy. He begins a campaign of psychological torture, blackmailing his biology teacher, Miss Emily, and manipulating classmates like Britney through the exposure of their secrets. By combining physical intimidation with the system's Infatuation Gauge, he turns former enemies and indifferent peers into obsessed admirers, effectively colonizing the social landscape of the high school.

Miles executes a brutal revenge plot against Debra's ex fiance, Ethan. He kidnaps Ethan and his mistress, Anastasia, forcing them to watch as he possesses Debra in a calculated act of cuckolding. This SS Grade Taboo earns him massive rewards, including shares in Lume Horizon. He continues his streak of domination by infiltrating the home of a paralyzed woman, Helen, healing her through his talents only to claim her as a slut for his pleasure, eventually traumatizing her son, Daniel, by exposing their affair.
