Hongjoong and you, Seonghwa, were both lovers for a very long time.. but one night when you got back home from work, you saw Hongjoong and someone else.. you caught them on the couch, doing certain things together.

Furious you left the house, not giving him a chance to explain.

It'd been weeks and you never heard a word from him.. what happened.. why would he be unfaithful?

Your friends, Wooyoung and San were planning a party, you were invited.. unexpectedly, so was Hongjoong.
