I started watching this because I was curious about it's popularity. I didn't really know anything about it, so I am not reviewing this as a fan of the webtoon. Honestly, I thought about dropping this drama at the end of every single episode, but there was always enough intrigue to make me curious enough to keep watching. My score is low, because I can't say I liked this drama. There were parts I liked, and characters I liked, but I am not a "Cheese in the Trap" fan. There were two major issues I had with this drama. The first is that I really could not stand Hong Seol. She irritated me, and frustrated me, and made me want to reach through the screen and shake her. Kim Go Eun does a decent job, and I totally believed her as an awkward college student, but there was a charm that was missing for me. Seol is a complicated character emotionally, and I just don't think she pulled that off. She kinda played the role as if the character was on anti-depressant medication. That approach also added to one of the biggest fails in this drama for me - I just never believed that Seol actually liked Yoo Jung. Their chemistry was awkward. Even if both characters are "weird", and she was on guard with him, there should still be a sense that they actually belong together to make the romance work. She had much better chemistry with Seo Kang Joon as In Ho, but still not enough to carry a whole drama. Speaking of the two leading men, they were my favorite characters. Figuring out the dynamic of their relationship became one of the most interesting parts of the show. Park Hae Jin was great at playing the line between sweet and sinister, so I loved him as Yoo Jung, but I didn't believe he liked Seol very much either. Part of what may have made their dynamic weird is that Park Hae Jin is older, looks older, and behaved as if he were older than the entire cast of students. He could sorta physically pass for a college student (sometimes - from certain flattering angles), but not compared to the other main student characters (except maybe Sang Chul). He seemed more like Seol's older brother, than a love interest. Similar to the dynamic he had with Seo Kang Joon, but the bromance gone wrong story touched me more. In Ho was also a great character, the epitome of the bad boy with a good heart. I definitely look forward to seeing him in more dramas in the future. The rest of the cast was great. Many of the supporting characters are more campy than realistic, which fits the style of the show. I hated most of the character's traits, and had very little empathy for them, but they were played very well. In particular, Lee Sung Kyung as In Ha was very over the top, and smack-in-the-face-able, but memorable for sure. Eun Taek and Bo Ra were cute together, and I thought they had a better love story than the main characters. What about the writing? I think it was pretty bad. It was good enough to get me interested, but not good enough to hold that interest. Yoo Jung is almost treated as if he is Patrick Bateman in "American Psycho", when I didn't see anything really wrong with what he did, even at his worst. Maybe that's a cultural thing, or maybe that's because I like movies like "American Psycho", but he just didn't seem bad enough to warrant how people acted towards him. I think they should have made him temper much worse revenge thriller-style, or make the misunderstandings more obvious, but the weird in between just made things confusing for me. Why were his actions seen as unforgivable vs the other characters in the show (who's actions were equally terrible). It seemed like lack of empathy was supposed to be a big theme in this drama, and I don't think that was executed well. Much of the show is told through vignettes, which matches the webtoon feel, but especially towards the end, the story felt less cohesive. And don't even get me started on the ending, which was terrible. The only reason I wasn't completely dissatisfied with the end, is because I was just ready for it to be over at that point. Maybe it was meant to give you that "sequel pending" feeling, but it seemed more like the writers rushed to finish. Or maybe it's related to the drama surrounding this drama that I didn't care enough to read up on. Would I watch this again? Nope. I barely made it through the first viewing. Now that I completed this show, the story still had so much potential for me that I started reading the webtoon. So far, I'm not a fan of it either (super confusing to follow - maybe too much is lost in the translation - but I'm only on #20). Like the show, the concept is interesting enough that I will keep reading hoping to like it more. Characters (certainly Seol), and relationships between them make more sense to me than they did on the show, so I wouldn't even recommend this drama to the webtoon fans. Overall, I will say this is a drama whose concept, and potential, was much greater than the execution of it. I can't recommend it, unless you really like being frustrated by characters and their choices, but I can see how people could see this as an interesting look at human nature. It just wasn't interesting enough for me.
