The moment Su Wan threw the engagement ring from the 18th floor, she thought the most unrestrained moment in her life was now. Until the diamond ring accurately smashed the floor-to-ceiling window of the office building opposite - and the man standing by the window happened to be her ex-fiance's big boss, Shen Du, the president of Shen Group.
In order to compensate for this sky-high price of glass, Su Wan was forced to accept a strange agreement: three times a week, he would come to make coffee. She thought this was just a humiliating job as a social worker, but she didn't know that Shen Du never drank coffee brewed by others, and she didn't know that he had no intention of returning the ring since he picked it up.
