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.
