is this good? I've been battling my self if i would lay a hand on this manhwa

It's great.

does this contains rape? sa? (please no) how great was this

Yes, it does contain a lot of TWs including SA, violence, prostitution, murder. But it is not between the protagonists. So if any of these are detrimental to your mental health please avoid it. Although the plot is well done, and it is an interesting story. Your call.
