A mysterious "Female Body Purification System" suddenly activates, pulling ten notorious scumbags into its clutches. First there's the serial-cheating finance hotshot, then the esports streamer who toys with people's feelings, and even the handsome top student who's dated countless girls. When they wake up to find themselves transformed into soft, pretty girls with fair skin, they're forced to complete "Virtue Training Missions for Women": dancing in Lolita dresses, experiencing level-ten menstrual cramps, and helping their best friends tear into scumbags...
"Ding! Host detected verbally insulting women. Punishment triggered: breast size reduced by two cup sizes!"
"Ding! Host detected indulging in lustful fantasies. Reward: a 24-hour menstrual cramp experience card!"
Staring at their suddenly enlarged chests in the mirror, the former playboys are on the verge of tears. But the truly terrifying part is that the System's final mission is to make them win over the girls they once hurt!
