On the day of obtaining the marriage certificate, Shang Qingyu was left behind at the civil affairs bureau by her fiancé Song Yang, who abandoned her to look for Shen Yao, a childhood sweetheart causing a scene. Heartbroken, she dialed the phone number of her childhood friend Lu Xingye, inviting him to come and get the certificate. The Lu family CEO arrived in half an hour, and the two registered on the spot. Song Yang regretted and begged for reconciliation, while Shen Yao successively resorted to underhanded tricks, ultimately ending up in prison. Under the protection of her childhood friend, Shang Qingyu walked out of the pain and welcomed her own happiness.
