Chae In Ha was supposed to be gone after having sex with Daniel, after all, they were merely casually dating without the necessarily demanding or expecting the additional commitments of a more formal romantic relationship. Yet when Daniel pulled her down to the sofa with him after they had washed up in his bathroom, she didn't resist him.
Daniel cuddled her and it felt kind of nice. Chae In Ha never had a long relationship because she was more interested in spending more sexual time together, than having an intense connection with her partner. You could say that Chae In Ha was a player since she pursued sexual gratification and dropped her partners whenever she was satisfied or the line becomes blurry.
Although it seemed harsh, in reality, Chae In Ha was avoiding emotional attachment to any man. Falling hopelessly in love with a man was equivalent to shooting herself in the foot. Men couldn't be trusted and even if they didn't leave, they would always cheat.
