High school life should be the best and most unforgettable time in everyone's life. We were still boys and girls at that time, we met each other, understood each other, and became secret lovers. We once made beautiful promises together, but due to various external factors, our love is no longer sunny and unrestrained. Everything makes our love fall apart, and the flowers will eventually fall when they bloom. This "The Vow" takes the love life of contemporary students as the main line, and describes the emotional journey of a rebellious boy who strives to break free from the constraints of society and family pressure from many aspects. Love made him grow, made him happy, and also made him taste the pain of bleeding from his heart. It expresses the typical values and attitudes of contemporary students, but they cannot escape the tragic ending.
