"Fucking... asshole..." Dunk cursed under his breath, his body trembling from the overwhelming sensations. Joong leaned in, voice low and vicious against his ear. "That's right," Joong growled, his hips snapping forward, thrusting into Dunk with increasing force. "I am fucking an asshole." For generations, the Boonpraserts and Aydins have stood side by side-two of Thailand's most powerful dynasties, bound by legacy, empire, and an unspoken promise to protect each other's interests. Now, that promise is becoming permanent through the upcoming marriage between the Aydin heir and the Boonpraserts' only daughter. Joong Archen Aydin is everything an heir should be: elegant, obedient, and impossibly perfect-the golden son shaped by legacy and expectation. Dunk Boonprasert, on the other hand, is chaos incarnate. Reckless. Sharp-tongued. The black sheep his family tries to hide behind polished smiles and public image. The two have been enemies since childhood-locked in a lifelong war of petty sabotage, brutal words, and fights that always turned ugly. But everything changes the night Dunk decides to give in to a moment's vulnerability and sleeps with Joong. His sister's fiancé. His lifelong nemesis. The one person he should have never touched.

Joong used to have a girlfriend. Dunk used to have a best friend. Now, neither of them have what they once did. After a messy breakup, Joong is surrounded by friends trying to cheer him up-but there's only one person who can make him smile like he used to: Dunk, the best friend he pushed away without a word. When Dunk shows up, there's tension, there's silence... and then, there's understanding. They may have drifted, but the bond never really broke. Then Joong proposes something insane: Let my ex think I've moved on-with you. Let her regret leaving. It's a wild plan, but Dunk agrees. Not because he wants to help Joong win his ex back-but because Dunk's been hiding burning desires he's never had the space to explore. And this might be the one chance to finally understand them-with someone he trusts. Even after getting back what both of them wanted,fate finds their way back to each other,tangled in confusion and desire. It was supposed to be a trade. A way to get back what they lost. But somewhere between blurred lines and late-night confessions,sweaty bodies tangled together, the question isn't who they want to fool- It's what they're starting to feel. Love, lust, and loyalty-this isn't just a fake plan. It's something real they never saw coming.
