Li Youran signed a three-year agreement with Ji Hanzhou, his business marriage partner, and each got what they needed. She thought it was just a transaction, but one day she found a college photo in his study - the profile of the girl in the photo was exactly the same as hers. Ji Hanzhou never called her by name, only "Xiaojiu". Li Youran gradually discovered that she was the first love Ji Hanzhou had been looking for for eight years.
