Five years ago, Yunho decided that he was tired of chasing after Jaejoong with no results. He got his friend Changmin to help him. Though there were problems, it worked in the end. The two are very happy with each other and their three year old daughter, and there is no animosity between them and Changmin, who ended up dating Onew a year later. However, difficulties arise with the arrival of someone Jaejoong hoped to never again see in his life. How will Yunho react to everything happening? Can he protect the family he so deeply loves, or will it be too much for him to handle?
