Btw, is it just me or is there really a possibility of Kim Young Goon's actually not being a murderer? I hope that's not that case, it would be way too cliche.
Wait a second, are you guys really criticizing Seo Kang Joon's acting? Are we watching the same drama. Despite some of the plot holes (which is common in the majority of dramas), I think the two first episodes gave me the reasons I needed to keep watching it. I like the characters and their interactions. And the plot seems to have lot to grow.
