Kim Dan should move away and start over. Forget horse face (Amnesia style) and meet a nice guy.
Ain't nobody gonna complain if a real man steps in . Redemption arc for horse face? Sure, he needs to BEG for forgiveness! But it doesn't mean Kim Dan should be with him in the end.
Now imagine how good this would be if it had a good plot.
Dear author,
Please recall the manhwa and start it over with a good plot. Ik you can do it. Please, oh please. How can you see the current plot and think it's good? Cho!
The worst kind of cliffhanger...........
