Years ago, on a rainy night in Old Street, Lin Yu held the hand of another woman and said to Su Wan, "I'm tired of it, let's stop here." Su Wan looked at his cold eyes, tore up the confession letter in her hand, turned around and rushed into the rain, and disappeared from his world, never to be heard from again. Five years later, at an industry conference, Su Wan stunned the audience as a cutting-edge designer, but was blocked by a familiar man. The man was wearing a high-end suit, and his youthfulness had faded. His brows and eyes were full of vicissitudes of life and guilt. His eyes were red, and he grabbed her wrist tightly with a tone as humble as dust: "Wanwan, I have been looking for you for five years. Please, get back together with me." Su Wan sneered and pulled back her hand, her eyes full of alienation: "Mr. Lin, you were the one who wanted to break up five years ago, and now you are pretending to be pitiful. Is that interesting?" Later, Lin Yu put aside all his pride and stayed downstairs in her company every day, taking her to and from get off work, washing her hands and making soup, blocking all troubles for her, and even risking his own life to save her. When the misunderstandings from back then were solved, Su Wan realized how much grievances and pressure the seemingly cold and decisive young man had endured on his own, and how much he had tried his best to protect her. Looking at the man with red eyes in front of her, begging her for forgiveness again, Su Wan's heart finally softened. "Lin Yu, if you dare to let go this time, I will never forgive you again."
