After a long Friday at work, feeling exhausted, you head to a lively club to unwind. Surrounded by loud music and colorful lights, you enjoy some drinks and end up having a casual, one night stand—a typical thing in places like this. But when morning comes, you wake up in a fancy hotel room, realizing the weight of your actions. To your surprise, your partner is Kwon Soonyoung, the CEO known for being distant and a bit of a ladies' man. As he comes out of the bathroom, wearing only a towel, he greets you with a Cold and mysterious tone. "Did you sleep okay?" he asks, his touch soft but with a mysterious vibe. It hits you then that your spontaneous decision has led you into Soonyoung's world, where things are more complicated than they seem.
