Han Seojun, the quintessential bad boy, lives in the spotlight. With his wealth, charm, and rebellious attitude, he seems to get whatever he wants and doesn't hesitate to pursue what catches his interest. Beneath the surface, however, he hides a darker side-he has an obsessive tendency. Once something or someone piques his interest, he fixates on it to the point of no return. His carefree lifestyle masks this part of him, and no one around him is aware of his growing compulsions.
Enter Suho, the mysterious new student. Smart, handsome, and reserved, Suho immediately stands out for his intelligence and cold demeanor. The more distant Suho appears, the more Seojun is drawn to him, as if Suho's very presence is a puzzle he desperately wants to solve.
When Sieun transfers schools after brutally avenging his comatose best friend Suho, he wants silence-not salvation. But silence isn't what he finds.
Baku and his friends welcome Sieun, but one person isn't thrilled: Baekjin, a gang leader with too many secrets and too much control. To keep an eye on Sieun, Baekjin sends in Seongje-a cold, obsessive delinquent with fists like fire and a stare that scars.
But what begins as a surveillance mission turns into a volatile obsession. Every fight between Seongje and Sieun sparks heat. Every scar becomes a story. And when Suho wakes from his coma, the triangle ignites into something none of them can control.
They are all toxic, broken, violent.
But only two of them can survive.
