In the university campus filled with youthful atmosphere, Jinhui (played by Zhang Han), Feng Song (played by Wang Xiaokun) and others made a "brotherly covenant" in the hope of maintaining their friendship. However, things did not go as planned. Feng Song fell in love with a beautiful girl named Zhu Ting (played by Shi Yufei). However, what he did not expect was that Zhu Ting's heart had already belonged to Jinhui, who was handsome and had the reputation of being a school grass. However, Jinhui only had eyes for Zhou Hui (played by Chen Qiaoen), who had a sexy and hot body. A tortuous and bizarre love triangle began. In a blink of an eye, ten years have passed. The former brothers and friends have entered society and gone their separate ways. One day, Zhu Ting organized a grand class reunion to bring old friends together again. When everyone recalls their youthful years, what kind of relief and feelings will they have?
