This was a generally easy show to watch in that I was able to watch it without wanting to drop it or needing a few days in between episodes. I was planning on giving this show a solid 8 until the last episode where everything just turned super melodramatic. I am of the mindset that not every villain needs be redeemed, especially when "redemption" for certain characters is not exactly believable. Unfortunately this show didn't believe in that concept. I don't care how much of a bleeding heart you have, some things are just not forgivable and even if they were, you definitely would not somehow turn everything around and blame yourself for someone else's shitty actions (talking about Cho In's and Sun Woo's father). Now coming in to this I knew it was a revenge story and that I would not find myself actually rooting for the villain (in general I hardly do) and that was fine by me. I don't have to like the villain, in fact I like not liking the villain. However, I do not enjoy watching a villain with absolutely no charm or charisma. To be frank, Sun Woo in general wasn't acted well. The actor felt completely one dimensional up until the very last scene of the show where finally I felt myself feeling something other than utter annoyance. It really frustrated me because Sun Woo is a multifaceted character who in another actor's hands might have come off brilliantly. I was not expecting to think much of Cho In at all because of So Ji Sub. I specifically watched this show after watching So Ji Sub in Ghost and being completely unimpressed by him. His1000+ hearts on this site baffled me and I wanted to find out what so many people saw in him. He was my absolute favorite in this show. First of all he looked adorable and secondly his wounded portrayal of Cho In just murdered my heart. I swear this man conveyed so much with his eyes, I just wanted someone, anyone to hug him at all times. As far as the female characters go, I actually really liked Seo Yeon. She was far from perfect and thank the TV gods for that, I like my characters to be as close to human as possible. What I liked most about her is despite dating two brothers she was upfront about her feelings. She stuck by her feelings and when the time came for her to prove it, she did. When Sun Woo asked her if she would stick by him even he did despicable things she meant it. A female who sticks by her guns and doesn't play with people's hearts? Yes please. Plus she was genuinely a sweet person. Young Ji drove me up a wall majority of the time. She was adorable at times, but mostly she came off as obsessive and stalkerish. Such a shame as she and So Ji Sub had really nice chemistry. Back Seung Hyun, who played Chi Soo, was so dedicated and he got my blood boiling, but it was such an awesome performance. In fact I found his relationship with Cho In much more interesting than Cho In and Sun Woo's because of his great performance. The side "romance" felt random and just "there". Didn't add much to the show at all. All in all the show was solid and if you need a reason to watch this show, So Ji Sub would be it.
