Seungcheol was deeply and openly in love with Joshua, and everyone knew it. Their parents had already decided on their marriage, and both the Alpha and the gentle Omega were ready to spend their lives together. Their bond was pure, mutual, and steady - the kind of love people felt grateful to witness. But Jeonghan, the master manipulator he always was, refused to accept it. Driven by jealousy and obsession, Jeonghan destroyed the wedding with his wicked schemes. One night of lies was enough to twist the truth, stain Seungcheol's image, and break Joshua's heart. What Jeonghan did forced both families into chaos. His actions didn't just stop a wedding - they shattered destinies. Joshua was pushed into marrying Seokmin, Seungcheol's calm and distant brother, while Jeonghan used threats and false evidence to trap Seungcheol into a marriage he never wanted. Seungcheol despised Jeonghan to the core, hated his presence, and refused to spare him even a single glance. But tradition came first, and duty always won. And so, the impossible happened. The twins married the opposite person they loved. What should have been a blessed union turned into a curse - and the problems only grew from there.

Chaos and destruction. Two things Lee Seokmin despised more than anything. He thrived on control, on order, on things falling exactly into place. But everything unraveled the moment he laid eyes on him-his new husband. The brother of the man who was supposed to marry him. Joshua. "I know you hate pineapple, so I made sure to eat a lot. Imagine if we kissed right now... You might die," Joshua's voice was sweet, but the mischief in his eyes was undeniable as he leaned closer, his smirk dangerous. Seokmin's jaw tightened. No one could hear them, not their bickering, not their hate, and most importantly, not the way Seokmin's dead heart seemed to stir back to life. He hated chaos, but Joshua was chaos. And now, he was stuck with him. How was he supposed to navigate a life of perfect control with a husband who thrived on disorder? Would they ruin each other? Or was falling together inevitable?

What's worse than a blade at your throat or staring down your own death from a cliff? Getting married to Choi Seungcheol - the man even devils prefer to avoid. Yet here I stand, wrapped in silk I didn't pick, under chandeliers brighter than my will to live, listening to vows that feel more like contracts signed in blood. Everyone says this marriage will end a war. Cute. I say it's another battlefield - one I intend to walk across in heels and sarcasm. Because here I am, in a wedding hall dripping in roses and danger, smiling like I'm not actively planning how to make my new husband stop breathing.

"What kind of creep are you? Stalking your own cousin?" Wonwoo looks up from his phone to see a tall man, dressed in basketball shorts and a jersey, his face flushed and breath heavy. "Sorry? Are you talking to me?" Wonwoo asks, pointing at himself. "Yes! You! Stop stalking Jia. Stop stalking my girlfriend!" Wonwoo freezes, his hands gripping his phone tightly, before he lunges forward, throwing his fist right into the other boy's jaw. "Why the hell are you referring to my girlfriend as yours?"

BOOK #4 He didn't walk into my life - he bled into it. Like smoke curling under locked doors, like rot blooming behind a smile. They say the Devil knocks. But Soonyoung never needed to. He found the cracks in me, the ones I sealed with silence and stitched with obedience, and whispered through them like a hymn - dark, low, addictive. He calls me little heart, like I'm something fragile he plans to keep broken. And I keep coming back, not because I'm brave - but because I've forgotten the taste of salvation. And damnation, when it wears his face, feels almost holy. ---- I never wanted heaven. Too clean. Too quiet. Give me the boy who flinches at kindness and claws at cruelty like it's the only language he knows. Give me Jihoon. My little heart with iron in his spine and rot tucked behind his ribs. He thinks he can outrun the dark - sweet thing hasn't realized I am the dark. And I've already wrapped my hands around his throat, not to hurt him - but to make sure he never leaves. He prays. I answer. Every time, in blood, in fire, in a love so sharp it cuts both ways.

Seongcheol must decide: will he fight the bond forming between them, or embrace the heat that threatens to consume them both?
