Guan Xiao and Jian Yi began to know each other when Jian Yi moved to the downstairs of Guan Xiao's house when he was nine years old. Their mother was an old classmate. From the first moment they met, they embarked on the fateful path of being happy enemies. After knowing each other for ten years, the two accompanied each other and cared about each other, but they also stubbornly avoided that unique feeling. In high school, Weiwei appeared next to Guan Xiao, and Lu Zhe appeared next to Jian Yi. They gradually discovered that each other's existence was so important. However, at an ignorant age and blindly escaping, this heavy love ended before it even started. If the love is long enough, the relationship will not be short. Six years later, the two met again and continued their unfinished love journey.
