Byeon Baekhyun, a member of the popular boy group EXO, signed a contract marriage with amateur heroine Lin Wanxing in order to avoid forced marriage by his family. During their cohabitation life, the two went from being strangers to falling in love, but found that there was a deeper bond hidden behind this relationship - it turned out that they had already appeared in each other's lives.
