When Lin Wan was packing up her mother's belongings, she dug out the confession letter she wrote to Zhou Chengyu when she was in college. A week later, she stopped the black Porsche in a heavy rain: "Teacher Zhou, are you still hiring interns in your studio?" He got out of the car holding a black umbrella, his suit trousers soaked in the rain: "Lin Wan? Long time no see." Working overtime late at night, he suddenly pushed the yellowed letter paper in front of her: "The answer that is seven years late, do you want to hear it?" The city outside the glass curtain wall was brightly lit, and when he kissed her, she tasted the bitterness of whiskey. "I received the letter." He rubbed the base of her ring finger with his fingertips, "It's just that year, my father had just jumped off a building." Later, Lin Wan found out that the ring mark on his ring finger was three years older than when she met him. She finally tore up the pregnancy slip at the airport: "Zhou Chengyu, we... Haven't started yet, have we?"
