Everyone has their dirty little secret, right?
An ordinary office worker like Dunk Natachai also has one thing that he keeps for himself for so long, it is his guilty pleasure. And it was all fine until one day his path collided again with an A-list actor singer named Joong Archen who looks like has so many problems in his hands.

They meet, they talk, they kiss, they fight, they have sex, and they... share another dirty little secret, but this time, together.
