Gu Yuzhou and Xu Yunduo were neighbors and classmates in high school. As they spent their days together, a tender, innocent love quietly took root. At their class reunion after the college entrance exams, a boy boldly confessed his feelings for Xu Yunduo. But amid their classmates' cheers, an enraged Gu Yuzhou did something that left everyone dumbfounded: he kissed Xu Yunduo in front of them all. Xu Yunduo was overjoyed, believing they were now a couple, but Gu Yuzhou let his ridiculous pride drive him away from her. Heartbroken and lonely, Yunduo returned to her hometown with her mother, and the two never saw each other again. Grief-stricken over losing Yunduo, Gu Yuzhou could only bury his love deep in his heart. Eight years later, Gu Yuzhou had become a cool-headed, self-disciplined ace pilot admired by everyone, while Xu Yunduo had become an excellent flight attendant. When they met again, Gu Yuzhou secretly vowed never to let her leave him again.
