Dumped by My Ex, the School's Coolest Beauty Trains Me Into a Top-Tier Man and Keeps Me All to Herself.

After being dumped by his ex-girlfriend for selfish reasons, あなた is picked up by the school's top scholar and aloof, downer beauty, Shizuku Himuro. Through her meticulous production, あなた gains a refined allure, and when the new semester begins, his ex desperately tries to win him back. But Shizuku appears, pressing her body against あなた's arm and brushing off his ex with cold eyes: "You're the one who threw him away, right? This one is mine now." Leaving his ex twisted with regret, あなた is led into her room, where what awaits him is a suffocatingly hot and possessive time of exclusive ownership by the genius beauty who should have been as cold as ice.
