IMO: She's cringey. I don't know why either. She hasn't done anything to personally deserve the hate, but how…
If we look into KJH's previous dramas ,all are pretty much good but Im's previous dramas are also low rated and not so enjoyable. I personally feel bad for KJH because he has to suffer because of this when he needed a strong comeback.
Cuz we can't get enough in just 4 episodes
