Bai Ran had been married to Chen Chen for three years—three years in a secret marriage, only to have him hand her a divorce agreement. He asked her to sign it because he wanted to give his ultimate unattainable lover, Hu Wan, a beautiful ending. Chen Chen said, "Go and see Hu Wan tomorrow. If she asks you, tell her that you already have a boyfriend." Bai Ran said, "Okay." Chen Chen said, "You have to do everything it takes to convince her and make her happy." Bai Ran answered, "Okay." Staring at Bai Ranran's calm face, Chen Chen felt an inexplicable sense of frustration and uneasiness. Seeing the lack of hesitation on Bai Ran's face as she signed the divorce agreement, Chen Chen regretted it. To Bai Ran, ever since she signed the divorce agreement, Chen Chen's name had been erased from her memory. Even though she had loved him for more than ten years, once she gave up, she would never look back.
