On the eve of graduation, Nangong Shuyu was about to confess to Bai Yang, whom she'd loved for years, when she learned he was enlisting. “I'll wait for you to come back, then we can get married.” But Bai Yang thought she was inviting him to her wedding to someone else. When he said, “Congratulations on your wedding,” Nangong Shuyu thought he was rejecting her. The two had no contact after that, until they met again seven years later when Nangong Shuyu went to a job interview. Seeing that her marital status was listed as “unmarried,” Bai Yang lost his composure.
