the first few episodes were really promising, the storyline, action scenes, there were lots of potential and i look forward on how the story will unfold. but then it just about them running away and hiding from the organisation, and it become repetitive. it becomes boring and draggy. i wish they could focus more on the science part, the l.u.c.a part, rather than just the relationship or maybe empathise more about the male is a monster or not. idk, the storyline was mehh. and as many other reviews, the last 4 episodes was ??? it became so messy and the once strong characters suddenly become so weak and stupid, everything is just emotional. i swear the plot was all over the place. andd all the difficult things previously became so easy like huhhh. and they make gu reum's revenge/ finding the truth behind her parents such a big deal, but then zuppp it end just like that. idk, maybe i expected a lot, the potential went to waste. i don't like this drama but i don't hate it too
