Story follows 4 rookies with very different past & personalities as they navigate through their 1st year of police work.

Rookie
1. Liu Da Wei is probably everyone's favorite with his sharp come backs. He's positivity takes after his mom (very few good mom characters in the show)
2. Yang Shu - exceptionally smart but very black and white idealistic cop
3. Xia Jie - Female character living the shadow of his father and over protective mom
4. Zhao Ji Wei - Not as likable initially as he's a country boy with obviously communication issues

Ep 1-9 I was hooked. Loved:
The mentor match up conflicts for Liu Da Wei and Yang Shu.
4 rookie's friendship under 1 roof
Growth in perspective with each case
Solid supporting characters
Liu Da Wei's witty comebacks, but I do think much is lost in translation

After Ep 9 I started to play at 1.5x speed for scenes with over exaggerated characters. Cops felt like door mats that villagers can yell at for whatever whenever.
There's too much expectations for cops that at some point it just felt unrealistic. "Protect & serve" apparently means that you need to be their fathers, mothers, psychiatrist, nurse, pay for the lock smith and hospital bills out of your own pocket. If you get slapped you'll need to just take it and apologize.
Think directors were trying to shoot that "warm fuzzy" drama but end up felt forced.

Ending wasn't bad. It tied up most of the lose ends but some stories didn't feel like it was truly resolved.
