Li Kaijie, who just graduated from college, fled to a small coastal town to find his ex-girlfriend Yi Mei. Here he encountered a car accident and met the beautiful landlady Xu Mengqi. With the help of Xu Mengqi and his friend Ajian, Li Kaijie quickly recovered and found Yimei. Later, he learned that Yimei had pledged herself to a Korean in order to go abroad. Li Kaijie was hurt and depressed. Xu Mengqi encouraged Li Kaijie to cheer up and infect him with her own hard work. Li Kaijie was moved by it and worked hard again. The two also gradually fell in love.
