"The Second Heartbeat of Childhood Sweethearts", protagonists: Su Nian and Lu Zeyan. Su Nian and Lu Zeyan were estranged due to misunderstanding, but they met again at the class reunion many years later. Lu Zeyan learned that she was encountering obstacles in starting her business, so he silently helped her attract investment and negotiate with customers. He worked overtime with her until late at night and stood up for her when she was in trouble. On a rainy night, he held an umbrella and confessed: "It was my fault back then. Don't leave again this time."
