Ruled by hormones

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.
