Seungho (POTN) The worst thing is that he has potencial of being a good character but at the end, he is a trashy psycho.
Yahwi (YTC) I have a special place in my heart for this awful bitch. If he is that lonely, why not hug his parents by himself? <3
Jiwon (BJ Alex) For having the worst character development ever. He literally cried once and those tears purify his soul out of nowhere.
