Overall I did not like this drama. I went in with high expectations since it had received so much hype and since I had seen most of the main cast in other dramas. My biggest problem with the show was with the characters so I will structure this review around them.

Hong Seol: As far as female kdrama leads go Seol isn't so bad. She's smart and eventually grows quite the backbone. My problem with this character was the way she acted with our male lead, Yoo Jung. She bent over backwards to accommodate him. Maybe I'm being harsh on her, as this is fairly typical kdrama female lead behavior, but it honestly bothered me that she seemed so blinded by his very consistent and predictable bad behavior. Also a point on Kim Go Eun; she plays all of her characters with too much of her own personality in them in my opinion. It's not that she plays every character the same, since Eun Tak from Goblin is nothing like Seol, but they all feel too much like Go Eun. I want to feel immersed in her acting and her real life personality is very distracting.

Yoo Jung: At the beginning of the show I adored Yoo Jung. I am a huge sucker for male leads with dark pasts and personal issues. He seemed perfect. Then came the stagnant to nonexistent character development. I am all about character's changing and growing with their experiences. Despite having innumerable opportunities to grow and change Jung remains stagnant. He never learns from his mistakes or changes his behavior. He never accommodates or changes for Seol even when she makes a huge effort to do so for him. He is the same problematic person in episode 16 as he was in episode 1. His chemistry with Seol is also nonexistent. They have nothing in common and the emphasis placed on how similar they are confused me throughout the entire show. His lack of growth was very disappointing to me. Despite being my male lead perfect type  in the end Jung fell flat.

Baek In Ho: He is my favorite character in this entire show. He shows an immense amount of growth and development going from a bratty thug to a respectable mature and caring adult, friend, and brother. Baek In Ho is what i wish the other characters were.

Baek In Ha: My least favorite character. I can write an entire essay with what I dislike about In Ha. She is shrill, immature, selfish, one dimensional, vapid, greedy, violent, arrogant, rude, untrustworthy, envious, and self serving. I could go on. Her character is just so unlikable in every way. She shows no remorse for any of her actions, at least no genuine remorse, and makes those around her miserable. Every moment she was on screen was torture to me. She too lacked character development and any moments where I was meant to feel sorry for her only made me hate her more. I see no redeemable features in her. A note on Lee Sung Kyung as an actress: I also saw her in Weightlifting Fairy Kim Bok Joo and hated her in that too. Maybe some of that carried over into my assessment and feelings for In Ha but nonetheless it happened. I do not like Sung Kyung as an actress. She consistently annoys me and her characters, whether sweet of bitchy, are not to my taste.

Eun Taek and Bora: I paired these two because they are a package deal. I wish more of the show focused on them. They were bright cheerful and showed a lot of growth for their comparatively small amount of screen time. I have no complaints about them and once again wish some of the main characters were treated with this level of character development.
