An unexpected encounter in the emergency room led the cold-faced CEO Gu Yanci to sign a "heartbeat contract" with doctor Su Qingyuan - he would take care of the family, and she would raise her brother's medical expenses.
As they got along, the contract gradually became true: Su Qingyuan used her medical skills to break the rumors, and Gu Yanci silently guarded her, from delivering medicine late at night to watching in the quarantine area, and even supported her in developing new drugs. Tests such as the epidemic and love rivals only made the two people's friendship stronger.
From the proposal on the mountaintop to the honeymoon at the beach, to Su Qingyuan's pregnancy, the initial contract turned into a lifelong commitment. The heartbeat of the emergency room and the tenderness of the CEO compose this love agreement that will never expire.
