Plus & Minus

On the night of their wedding, Zheng Ze Shou becomes drunk and gets jealous upon seeing a photo of Fu Li Gong together with their past classmate, Xiao Yu. He drifts off to sleep and dreams about their high school days.

Born only a day apart, Zheng Ze Shou and Fu Li Gong have been inseparable ever since their childhood; now as adults, they live right next to each other and even work for the same law firm.
