Gu Yuzhou and Xu Yunduo are neighbors and high school classmates. In the daily companionship between the two, their ignorant love quietly grew. At the class reunion after the college entrance examination, a boy boldly confessed his love to Xu Yunduo. Unexpectedly, amidst the cheers of his classmates, the angry Gu Yuzhou made a move that stunned everyone - he kissed Xu Yunduo openly and boldly. When Xu Yunduo was full of joy and thought that the two were already boyfriend and girlfriend, Gu Yuzhou fled Yunduo because of his ridiculous self-esteem. The sad and lonely Yunduo followed his mother back to his hometown, and the two never met again. Gu Yuzhou regretted losing Yun Duo and could only keep this love deep in his heart. Eight years later, Gu Yuzhou has become a calm and self-possessed ace pilot who is respected by everyone, and Xu Yunduo has also become an excellent flight attendant. When they meet again, Gu Yuzhou secretly makes up his mind that he will never let her leave again.
