━━━━━━ ✶ To the rest of the world, Kim Seungmin is the quiet, unassuming mechanics student who keeps his head down, does his work, and stays out of trouble. ​To Seo Changbin, he is the biggest, most infuriating headache on two legs. ​Changbin lives life in the fast lane-literally. He's an illegal street racer, a certified playboy who never keeps the same girl around for more than a night, and someone who doesn't take attitude from anyone. Except, for some reason, he lets the campus good boy push every single one of his buttons. ​Behind closed doors, Seungmin loses the shy act. He's a brat. He lives to get under Changbin's skin, deliberately pushing boundaries just to see how far he can go until Changbin snaps. Because Seungmin doesn't just want to tease-he likes when Changbin loses his temper. He loves the friction, the heavy-handed discipline, and exactly how it feels to be completely manhandled by someone who could crush him if he wanted to. ​Changbin claims he's just teaching the brat a lesson. Seungmin claims he couldn't care less who Changbin brings home to his bed. It's just a game of control. A dangerous, toxic little cycle of friction and heat. ​But when the smoke clears from the tires and the attitude drops, the line between playing a game and falling hard starts to blur. And neither of them is ready for what happens when they finally crash. ━━━━━━ ​Trope: Brat x Brat Tamer • Mechanical Student x Illegal Street Racer • Slow Burn • Toxic Comfort Warning: Contains themes of manhandling/rough handling, bratty behavior, use of alcohol , smut and heavy tension.
