Just a simple kiss

When a person knew when he was going to die, his first reaction would be fear. That was normally the case and that was what Chunhee had felt. After that fear came his anger, boiled from the main reason of his death. That reason was none other than Park Yujin, his future fiance. 

Thus, Chunhee had come to terms with himself and decided to plot his survival. By trying to change some parts as the "major points" couldn't be undone as another being had mentioned and threatened, Chunhee began to think of ways to alter the main event that caused his death―wedding. 

Chunhee thought, if he was able to stop his wedding with Yujin, he would avoid his downfall. But something as cancelling the wedding would mean cancelling the engagement first. Because he couldn't change those major events, then the only person who could such a thing was Yujin. He was the only one who could stop the engagement and wedding.

All of these things were all known by one person - Chunhee.
