Heeseung was your fiancé, and you were about to marry him, but he didn't show up on your wedding day. His parents told you he had died in a car accident. You promised yourself that he would be your last love and that you wouldn't fall in love with anyone else. You visited his grave every day, sharing your thoughts, problems, and stories with him.

three years later, after visiting his grave again, you decided to take a walk in the park before heading home. That's when you saw him—alive. At first, you thought your mind was playing tricks on you because you missed him so much. But as you were about to approach him, a young girl ran up to him, calling him "Daddy," with a woman standing behind them, smiling. You had believed he was dead all these years, only to find out he was alive, married, and living a happy life with his family while you were struggling without him.
