My Reviews:
1. Ou Hao and Li Yi Tong's performances were commendable, bringing depth and authenticity to their characters. The supporting cast also delivered strong performances, enhancing the overall viewing experience.
2. The story was good, but it is also a typical crime drama with a predictable outcome.
3. By episode 7 or 8, I had figured out that Chen Jia Dong (played by Eric Le Yang) was a murderer.
4. While the story was engaging, it could have been more impactful if it was condensed to 8 or 10 episodes. Adding two extra episodes made some parts feel prolonged and repetitive, which could have been avoided for a more dynamic viewing experience.

I give it 7.0 for good acting.
