Yi Shui is a freelance photographer. She has a boyfriend Yang Guang who has been in love with her for eight years, and two best friends Ran Xiaomeng and Xia Xia. When Yi Shui was about to get a marriage certificate with Yang Guang, she saw Yang Guang holding Ran Xiaomeng's hand and telling her that they were married and asking for her forgiveness. Yi Shui pretended to leave calmly, but was actually deeply shocked. Xiang Ran, the owner of a car 4S shop, has been divorced from his ex-wife Shi Hui for many years, and his good friend Chen Liang is his right-hand man. Xiang Ran and Yi Shui were originally from two different worlds, but because of an email sent by mistake from their assistant Xia Xia, they began a series of heart-wrenching love stories. When Xiang Ran and Yishui were preparing to get married, Shi Hui came back with Xiang Ran's two twin sons.
