This show was incredibly good at making me unable to stop watching; leaving me with excitement and questions at the end of every episode.

STORY
the plot was very full of so many surprises and events. some may think there were some useless ingredients like i've heard about his brain tumour and wonseok's fake gf but I enjoyed it nonetheless. This is such a captivating show and i had much fun watching it. However, parts of the plot lacked some logical explanation. I also wish the ending was more resolved as we dont see what happened to gi osung or really jaebum because the question is does jaebum really deserve to be punished for it when he has a mental disorder AND he was manipulated by gi osung (who is assumingly dead because, again, we dont know exactly what happened but he is probably dead as he isnt shown in the end) so should he really take the blame? i wish that was resolved as well as ji sooheon's brain tumour because while it is an open ending, i think if you are going to bring in something huge like a dangerous brain tumour and make us worry, you might as well at least indicate how it ends for him. because that whole thing is arguably not contributing to much of the plot anyway so why make us worry and the other characters worry too. we also didnt go into depth on how this brain tumour can really affect real life people as representation

CHARACTERS AND ACTING
I think jaebum's actor did very well at portraying his character's split personality disorder and each 'person' inside him. The rest of the cast did well too, though i dont think this script and writing unleashed any of their full potentials. The characters were all interesting and none annoyed me that werent supposed to. Ok chanmi and ji sooheon's chemistry was so perfect and i loved all their scenes together. despite not being a romance drama (and i am very mad we didnt even get a kiss) they're relationship made me giddier than many romance dramas i have watched and the main characters were mostly likeable. However, ok chanmi's character lacked logic at times, believing things way to quickly then acting on those thoughts such as when she heard gi osung telling jaebum that it was park wonseok who pushed him off the building and chanmi immediately believed it, sent out apology/goodbye videos and left even though gi osung was a very obviously untrustworthy character which annoyed me.

In conclusion, I would definitely recommend this show because I personally love it and it was so incredibly gripping with a loveable main cast.
