Art student Su Nian and entrepreneurial CEO Lu Shiyan became connected due to a heavy rain and a ginkgo illustration, but they drifted apart in the shadow of their native family, calculations in the workplace, and layers of misunderstandings. They reunited two years later. Although the truth came late, the sensitivity of love, the helplessness of reality and the courage of grinding eventually made the two miss each other in the dim light of the evening light alley. This is an urban regret about not daring to love and not being firm in faith. It is also a heart-wrenching farewell hidden in growth.
