why do ppl hate blondie again?

How sub was the stalker, and he also tried very hard to break them up.

i find the sub incident very funny because sungjoon doesn't even know that the sub was doing that lololol and he tried breaking them up because he thinks that this isn't the hwayoung he knew so i kinda understand where he's coming from because he doesn't like seeing hwayoung faking who he is and act all inlove when in reality, he's just a sadistic bitch who don't know how to love properly
