Oh but of course you can dislike characters! That's absolutely fine. What's not fine is to come with morals as if you're inside the story and the characters were to listen to any of your preaching. I've read many people preaching in a hardcore way! Like trying to change creators stories entirely! Like the free use of any elements in life were forbidden. It's insane lol
...not accept any freaking moral preaching (not that I've cared about it before) but this is a fictional series. And liking the development, positive or negative, in a character never means anyone supports this kind of behavior in real life.
If you have no ability to enjoy the dark depth of these kind of stories and their characters, you can kindly fuck off.
There's no "oh poor baby" on these stories. All characters have a past that have led them to act like that. It's like when you all go "poor Na-kyum, protect the baby!" First, he's a man. Not a little boy. Second, Seungho went through some pretty messed up shit. So, yes, you can have favorites with stories like these alright, but no one needs to be pointed at with the finger, especially in stories with such blurry morals. It's a genre. Don't like it, don't read it and shut the fuck up
