A real-estate agent Li Peiru gets drunk at a karaoke bar and throws up on a lonely cop Fang Zhendong.

Zhendong quickly feels a connection to the flirtatious Peiru despite the fact that she is having an affair with her married boss.

To make matters worse, Fang loses his job as a police officer after using an official vehicle for personal purposes.

As Fang's condition worsens, he finds himself forgetting more every day, which makes taking care of his new child difficult and frustrating.

After days of keeping constant vigil by his bedside, Peiru becomes sick and passes out just as Fang's heart stops beating.
