[Ongoing] Hearts in the Crossfire // Jikook by Wren3021

Jimin and Jungkook are the deadliest agents in South Korea, masters of a world most will never see. Seoul and Busan know their names only as whispers, criminals fear them without ever having seen them, and their teams respect them without question. Silent, disciplined, and impeccably precise, they move through the shadows as equals - lethal, untouchable, and unbreakable. Every mission demands perfection, every failure is unthinkable, and neither has ever faltered. When Jungkook is finally transferred to Seoul, he arrives with a reputation that precedes him - a lifetime of expertise honed in the underworld of Busan. But nothing could have prepared him for his new partner: Jimin, the agent whose skills rival his own, whose focus is absolute, whose presence is magnetic. Together, they are flawless, moving in sync with a precision that borders on instinct, a partnership forged in discipline and danger. Yet even the most controlled minds can be unsettled. Long nights spent planning, tracking, and confronting the darkest criminals slowly blur the boundaries between professionalism and desire. Trust deepens into tension, tension simmers into something more dangerous, more intimate. In a world where every secret is a weapon and every emotion is a vulnerability, the one risk neither expected is the pull they feel toward each other. For agents who live in the shadows, who thrive on control and strategy, falling in love is the most perilous mission of all - and yet, neither can resist it.

He gave her his vows. She gave her heart to someone else. Jungkook thought he had the perfect marriage-until the day he discovered his wife's secret affair with his biggest rival.

So Jungkook turns to the one person he knows he can trust: Kim Y/N, his loyal and brilliant secretary. All she has to do is pretend to be his girlfriend-long enough for Jia to finally sign the divorce papers. It was supposed to be an act. A game. A perfect lie. But when late nights blur the line between business and desire, and stolen touches start to feel dangerously real, Y/N realises one truth she can't escape: She's falling for a man who may never be hers. And in this game of love and betrayal, someone's heart will shatter first.

The Trouble With Kim Teahyung by LifeOfMe1992

🌸 Synopsis for The Trouble With Kim Taehyung 🌸 Y/N thought working as BTS's new stylist would be her dream job. The music, the fashion, the backstage buzz-perfect. Until he showed up. Kim Taehyung. Annoying, infuriating, and way too good-looking for his own good. From day one, it was war-sarcasm traded like daggers, glares across dressing rooms, accidental brushes that felt way too charged to be ignored. Everyone else thought it was harmless bickering. But Y/N knew better. Because trouble with Kim Taehyung wasn't harmless at all. It was dangerous. Addictive. And one wrong move away from becoming something neither of them could hide. Between stolen glances, late-night fights, messy confessions, and the one kiss that changed everything-suddenly, Y/N isn't just styling Taehyung for the stage. She's falling for him, hard. But when you fall for the most watched man in the world, love isn't simple. It's secret meetings, jealous fights, risky choices, and the constant fear of being caught. Because falling for Kim Taehyung isn't the real problem. The real problem is what happens when the whole world finds out. ✨ Enemies to lovers. Banter. Slow-burn tension. And the kind of love story that's equal parts chaos, steam, and heart.
