Yeonjun is the kind of guy you can’t take your eyes off. Charismatic, breathtakingly attractive, and exuding confidence laced with sarcasm—he draws people in effortlessly but never holds onto anyone. Relationships? Love? Commitments? Not his thing. Just fleeting nights, cigarette smoke, and the thrill of being unattached. He’s the perfect bad boy, and it has always worked in his favor.

But then there’s Beomgyu—his complete opposite. Loud, playful, clumsy, always laughing like the world is one big adventure. They couldn’t be more different, yet somehow, Beomgyu is the only person Yeonjun keeps coming back to. The only constant in his life.

And then Beomgyu's new boyfriend appeared. Someone else holding Beomgyu’s hand, making him smile, looking at him the way Yeonjun never allowed himself to. Suddenly, Yeonjun was angry for no reason, lashing out, picking fights. He hated that guy—hated him to his core. But the worst part? He would never admit why. Not to anyone. Not even to himself.
