Sunghoon and Ni-ki (You) are sworn enemies from rich class families. Both of their parents know each other very well, but they didn't start off in good terms. So they were enemies from childhood. But to fix their problems, their family forced them into marriage.

Their marriage looked flawless at the first, with the both of them bickering at any chance they get, but Ni-ki finds Sunghoon in the room at night crying and weeping quietly.

He was sitting on the bed, with his back faced to Ni-ki as he entered the room.
