I honestly believe that Kang Chan's story is an interesting one. However, if you've come here because of "Get Schooled", "Bad Person", and others, then I am sorry to burst your bubble. 

What makes first season good is the ability of the author to create cliff-open hangers. I would like to acknowledge the ability of the author to pis*** off their readers by going beyond what reader's expected to happen because after all, that's what makes you a good author. 

But then, if you continue to use such tactic overtime, the story gets boring and enters a cycle that has no development at all. 

That's what happened when the main character finishes off a villain right away, then the villain comes back, then play, until it's become a cycle. 

Overall, it's a good story. But, writing wise? I'd say it's solely relaying on the fact that it can irritate the readers. 

For this, I rate the story 6.8/10. No, make that 7/10 out of then because of complex characters like Smithen, Kang Chan, and the Italian blonde. 

Is it a good read? Yes, I guess.
