After three years of marriage, Li Shu was the number that was always pressed on Wang Yanting's cell phone. He remembered that Su Wantang drank coffee without sugar, but he could not remember that his wife was allergic to seafood. On the day Li Shu received her physical examination report, Su Wantang came to pick her up - wearing her husband's coat, holding the car keys she gave her, and saying with a smile, "Sister, get in the car." Li Shu didn't argue, she just cut off her long hair that she had kept for three years, leaving behind a signed divorce agreement and a letter with only five lines of words. Wang Yanting thought she was just losing her temper. It wasn't until the court summons was sent to the company that he discovered that she had even canceled her mobile phone number. He searched for her like crazy, searched through the surveillance cameras, chased her to her studio, and found the investigation notes she left behind - which contained a truth he had never thought of: his mother's death seven years ago was related to Su Wantang. He finally understood why she left, but there was a long queue of three hundred people for her book launch, and he stood at the end. The embers will not rekindle, but they are just enough to warm a person in the palm of your hand.
