Kimhan proposed to his girlfriend Mookrin. But ever since Kimhan's sister was believed to be killed by Tada, who's Mookrin's brother, Kimhan's attitude is completely changed. Charges against Tada were dismissed Mookrin provided testimony proving Tada was at home at the night of the incident. Kimhan is certain that Mookrin lied to help her brother, and begins his plan of a revenge. He calls off their engagement and gets married with his ex-girlfriend Paktra instead, in order to humiliate and hurt Mookrin.

Mook's friend criticizes Pak for snatching Mook's husband online. Mook's friends even go to Pak's store, and end up being reported to the police station altogether. Kim and Mook rush over to check what's going on. Pak is resentful to see the two being together. Kim and Mook start to fight in the office, but they only seem like some couple having random bickering to their colleagues.
