Campus bully Lu Rong keeps a low profile, quietly amassing wealth through his hard work and wit, transforming the school’s underworld forces into a money-making machine. He’s hailed as the business leader of Chengnan High School. One day, the rich and handsome school idol Ji Wenfeng makes a grand entrance, causing a stir with his stunning looks and terrifying financial power. Lu Rong exclaims, “What’s so great about being a rich second-gen?!” But when he returns home, he finds out his aunt has married Ji Wenfeng’s father. Now, he has to tag along as an unwanted stepchild—eating Ji Wenfeng’s food, riding in Ji Wenfeng’s car, and living under Ji Wenfeng’s roof. Ji Wenfeng sneers, “What’s so great about being a rich second-gen?” Lu Rong: *“…It’s pretty great.”* Ji Wenfeng: “You’re just a little brother.” Lu Rong: *“Big brother~”* Ji Wenfeng: “In this house, you obey me. From now on, you’re my little slave.” Lu Rong nods meekly: *“Okay, I’ll go wash your clothes then~”* —Only to mercilessly auction off Ji Wenfeng’s wardrobe the next second: *“Genuine limited-edition hoodies fresh off the school idol—starting bid ¥3,500! Don’t miss out!”*
