Character development doesn't mean the character positively change and do the right thing that everyone wants. Character development can be nagative, it's any change in the character. There's character development with both Keith and Yeonwoo but it's not well not written because the characters themselves are not well written.
I think some of you don't understand the meaning of character development. In this case there hasn't been character development for Keith at all. Just because he's worried about Yeonwoo and the baby does not mean he's had character development. None of that erases what he's done. In my opinion he will have character development when/if he realizes what he did to Yeonwoo was wrong and he ACKNOWLEDGES that he raped him, he needs some sort of professional help and in my opinion he should apologize to Yeonwoo for the rest of his fucking life. To add to that, we've mainly seen the story from Yeonwoo's perspective, we didn't see Keith himself go through this so called "character development," we just out of nowhere see him being kind to Yeonwoo. If this is what character development looks like in this story then I'm sorry but the writing is awful and it just fetishizes rape.
