Season one is so much better than season two. IMO the plot for season 2 is a bit weak compared to Season 1, I think KHI has already done enough revenge for Lee Sang Yeon in episode one of S2. Why does he want to find out who the biggest drug dealer is? no need . The intention is just to bring justice to Lee Sang Yeon, right?Compared to S1, KHI is trying very hard to find the cause and who killed his mentor in order to protect his mentor's good name which has been tarnished. This plot is stronger because it involves more people conspiring to cover up the murder case.Overall okay, as many people say, there are a lot of slapstick jokes, comedy that are forced and is not feel like S1 vibes.
