Seungcheol knew Jeonghan, a bit very well. It was a high school rivalry that never ended. It was dragged so bad that in the present, Seungcheol and Jeonghan even clashed in a meeting of BSK with Rose Quartz with of course an excuse. But thanks to the CEO, Boo Seungkwan, everything settled down. It was a long story to be honest and Seungcheol knew that he would recall a lot of sour memories in the following days. Because his younger brother, Choi Seokmin was going to marry Jeonghan's younger brother, Yoon Joshua. But things took a 360 degree turn when his mom revealed an unexpected proposal, for him and Jeonghan. And what will happen when an anonymous identity tries to take control of Seungcheol's life? Happy Ending

"Hyung!" Mingyu barged into Seungcheol's cabin, "Areum- did you hear that? She's no more." Seungcheol smirked, "I knew this would happen." "Hyung? Sorry to say this, I'm glad this happened but she was your fiance?!" Mingyu gasped, "What if some enemies of ours killed her? We need to show them our power." "Don't be sorry. I got engaged with her not because I wanted to marry her. She was just a mediator for me." Seungcheol stood up, "Second, she isn't killed by our enemies for sure. I just needed some clues." "Clues?" Seungcheol nodded, "I want the person who killed her in front of my eyes. I want to ruin this pretty devil, for sure!" "Are you talking about-" Mingyu realised. "Yes. Let's see how long he can hide his identity." Seungcheol chuckled wickedly, "I'm coming for you, my sinister love."

What happens when the supposed to be parents of the group disappeared and left everyone in a dilemma? This book will have exactly 13 chapters! Celebrating the ninth debut anniversary of Seventeen! - Happy Ending

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.

"You know Ara." The King sighed, "Seungcheol is still grieving over his lost soulmate. He needs to marry and attain the throne, it's his responsibility." "Will his soulmate not reincarnate?" Mr. Kim looked up. "She was cursed, we all know that." "I know, enough is enough. As his mom, I've a plan to bring my son on line. Someone will play the role of his reincarnated soulmate until he becomes sane again." "Who?" "Our Royal Advisor's son, Yoon Jeonghan." Fire and Ice can't exist together, can they? Happy Ending

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?

Seungcheol cherishes every moment of them being together while Jeonghan isn't even aware of his first love's existence. But they met again, as unexpectedly as they had parted ways. And now, Seungcheol is determined to bring his incomplete love story back to life no matter what. "You're here." "Yes, I Found You." Happy Ending

BOOK #2 They say love heals scars, but Seokmin's scars were lessons-bitter reminders that twisted him into a creature of darkness. His life was a series of brutal lessons that shaped him into someone who burns with an unquenchable fire. Protecting his brother-in-law's assistant was both his best and worst decision, a choice that bound him to Joshua in ways he could never escape. Joshua was his-body, mind, and soul. His to break, reshape, and claim. No one could alter that, not Joshua, not even Seokmin himself. Seokmin's voice was low, his breath hot against Joshua's skin as he spoke, "I've never craved anyone as much as I crave you." Joshua's eyes were wet with fear as he tried to pull away. "You don't love me. You're just obsessed. Let me go." Seokmin's grip tightened as he leaned in, pressing his lips to Joshua's in a kiss both tender and demanding. "I'll let you go," he whispered against Joshua's lips, "but only when my soul is ripped from this body. And even then, who knows? Maybe we're bound beyond this life."

BOOK #1 "I'm not just a pretty face, Seungcheol. Underestimate me at your own risk." Jeonghan glared at Seungcheol, stepping into his personal space. "You might be a model, but you've just walked into a whole new kind of runway - my world." Seungcheol husked out as he grabbed Jeonghan's jaw, tilting his head up and connecting their lips. One year, without a single slip-up. That's all Seungcheol needs - a marriage of convenience to divert media attention and stabilize his company. But what he didn't anticipate were the distractions Jeonghan would bring into his meticulously controlled life. The real catch? Convincing Jeonghan, the boy he once rejected in high school, to agree to this arrangement. Can they survive a year of this delicate dance, or will old wounds and new sparks complicate their plan?

BOOK #3 He's like a storm-unpredictable and dangerous. I knew he was a sick bastard when he smiled after I hit him the first time. Annoying and obsessive, that's what he is. I sensed it early on, but I didn't realize just how deep it ran until his obsession latched onto me. Until I became the center of his world. Until he started flashing that smug, crooked smile my way. But we can't... we're not supposed to be together. We're polar opposites-existing in the same world, but never meant to collide. Yet, he's ready to tear down everything for me. But it's not that simple. My brothers are monsters. They'll kill him. And still, he doesn't care. ---- Glasses perched on his nose, calm and collected. Exactly my type. I knew he was meant to be mine the moment our eyes locked, that intense gaze pulling me in. And I'll have him, no matter what it takes-by any means necessary, even if it costs me everything. I want to hold him in my arms, kiss him until neither of us can breathe. But why is it so hard? Why does the world push back so fiercely when it comes to him and me? I want him. And I will have him.
