He wasn't supposed to be mine... but I'd burn the world before letting him go Seungmin always believed in control. Control over his emotions. Control over his life. Control over who he falls for. So crushing on the untouchable, dangerously beautiful Hyunjin? That was a mistake he could ignore. But falling for his stepbrother- Lee Felix. The boy with sunshine in his smile and chaos in his veins? That was a disaster he never saw coming. Because Felix isn't just light- he's jealous, possessive, and dangerously addictive. And the more Seungmin tries to stay away... the harder Felix pulls him closer. One kiss turns into tension. Tension turns into obsession. And obsession? It destroys everything. Secrets begin to surface. Trust shatters. And love starts to feel like a war neither of them knows how to win. Because in a world where feelings are messy and choices have consequences- loving Felix might be the biggest mistake Seungmin ever makes... ...but walking away from him? That might just break him completely
