Thirty-two-year-old architectural designer Liu Haoran's life was as accurate as the blueprint in his hand - until he reunited with his first love Lin Yuwei, whom he had not seen for ten years, at the site of a community renovation project. She is the person in charge of children's charity projects. Her smile is still warm, but there are fine lines at the corners of her eyes. The pain of parting without saying goodbye ten years ago still remains in each other's hearts. Now they are strangers who must cooperate.
Cracks began to appear in Liu Haoran's world. The late-night blueprints turned into her face, and the perfectly planned plan hesitated in front of her. Lin Yuwei was also suffering from insomnia - she thought she had forgiven her long ago, but her heartbeat could not lie. When the old locust tree in the old community was marked and removed on the drawing, she said softly: "This is the place where we had our first date." The pen in his hand suddenly stopped.
There is no black and white in adult love, only countless gray areas. Ten years ago, they were too young and did not understand that explanation is more important than love; ten years later, they have learned too much and dare not ask, "How are you doing?" When the project faced a crisis and the truth of the misunderstanding from the past came to light, they discovered that the best reconstruction is not to go back to the past, but to grow together on the ruins.
