It's hard to change your feelings, and it's really hard to treat you. The two people, who were known as talented men and beautiful women during their college years, were deeply in love with each other. After graduation, due to work reasons, she chose to go to other cities and made an agreement with him that she would come back two years later to build a future together for the two of them. However, an accident made her choose to "give up" on him who loved her dearly, but he never gave up. For a promise, he waited for her at the agreed place. He firmly believed that she would come back. She's back, but will she still be the same person?
