Because its been hard for me to keep up with the different volumes on here, I'm reading it online, I'll put the synopsis.

Things didn't end well for Min Jieun, and now Oh Sangwoo and Yoon Bum have a body on their hands. Can they dispose of it without getting caught? And what will Officer Yang Seungbae do when he finds out that Oh Sangwoo was the last person the missing girl was with?

But this was so interesting with each of their characters evolving, the whiplash of personalities from Sangwoo is intense though.
