Then, at the age of 18, she was paired up with playboy Park Yoochun in a marriage of convenience. While he was adamantly against it, she had no solid reasons to object and the empty wedding commenced. However, when complications make her question everything about herself, Bom soon discovers the meaning of truly living for herself.

Park Sandara gives her kindergarten students one last life lesson before they leave her classroom and move on to the first grade.
