i disagree. there were a lot of instances where seungho felt regret and showed worry even though it's slight which is, in my eyes, character development. does it change the fact that he raped nakyum? no. of course not. but i don't see how this is an indicator or excuse really for having absolutely 0 character development whatsoever.
this started out relatively well too, the rape scene in the pavilion (?) was extremely uncomfortable to watch for me and i did not feel even the slightest hint of romance. the more romantic scenes afterwards were obvious signs of stockholm syndrome but frankly, i didn't mind as much since seungho started developing feeling for nakyum as well. the two of them getting sick afterwards was a weak and way too common plot device but it's usually used as a trigger for character development so having hope was understandable.
yeah no fuck seungho no excuses for his behavior whatsoever... every hint of character development went down the drain apparently? he's just being a dick
