Changmin and Yoona has been together for almost three years now. Like all other couples, they've had their ups and downs, mild to wild fights, and cool off moments. Despite this, they've maintained a relationship that is going strong day by day. As their third anniversary approaches, however, Changmin felt the need to break off the bad news to Yoona: SPLIT UP TIME. Can Yoona convince her way back to Changmin's heart or will the heartthrob remain stone-hearted? All the more, has the feeling changed for Changmin or is breaking her belle's heart the best way to prove his love for her? Ultimately, do goodbyes really come with second chances?
