Also I think some people hated at first just because she was an obstacle.
Obstacle? Obstacle to what? The torture and death of bum? Right now that distgusting inhuman thing enjoys himself so at least bum will live another day.
When Jieun was introduced people kept treating her like an obstacle between Yoonbum's and Sangwoo's relationship.
People treat it like that but the only relationship so far (ch17 ) between them is one of a killer and his victim.
Yeah but some want the killer and victim relationship, to change to serial lovers that kill for a hobby.
Some people are really cruel I mean I know Jieun acts like a bitch, but she really didn't deserve what happens to her. I mean I don't like her but she is only human, and to be honest most people can be horrible when angry. She is just a jealouys girl who takes her mocking to far but she didn't know what Yoonbum has gone through. I just pity her for falling for Sangwoo's trap and manipulation, by the way Yoonbum also fell for Sangwoo in the same way. I don't like Jieun's character but people do show a ugly side to them when jealous.
