Just watch Season 1. Its incredible and amazing. I loved it.

I will suggest you to not to watch it. Such a bad plot I have never seen. I wasted my time watching 9 epi so you should not do it. Just watch Season 1. Its incredible and amazing. I loved it. Park Hae Jin character is lovable in season 1. But please don't waste your time here. You are surely gonna regret like me. So please even if you have started then stop please. They will kill one of the main character in epi 8. And don't even have his proper funeral. I really hate that. I was watching it because of him
