"Prosecutor Mo Ming & graduate student Xu Qiaoyue + age difference"
Their acquaintance started with a bad story. Xu Qiaoyue, who had just returned to China, was knocked into the water by Mo Ming who was chasing a suspect while on a cruise. Although she was rescued ashore in time, this incident caused Xu Qiaoyue to misunderstand Mo Ming.
The lovelorn Xu Qiaoyue and the divorced Mo Ming have many opportunities to interact with each other because of their daughter Lily.
In the subsequent interactions, Xu Qiaoyue discovered that Mo Ming was actually a charming and warm man, not as scary as the legendary 'ghost-seeing worry'. And Mo Ming also fell in love with this gentle girl during the process of getting along.
The two have known each other for many years, and both have their own worries. Is it a happy ending in the end, or do they all go their separate ways?
