Ever get drama amnesia? For some reason, I could not remember ever watching this drama. I didn't rate it, or review it, and I couldn't remember any of the plot... I just had this vague familiar feeling about it. Normally that's a bad sign, but not in this case. I finally decided to watch it, or rewatch it, and I don't know how I could've forgotten something so good. As I started to watch each episode, I could feel certain plot points coming back to me, but not completely... slowly, withe each episode. Knowing what would happen didn't stop me at all from becoming addicted to this show, and eager to watch what happened next. The writing, direction, and cast were all THAT good, Gong Hyo Jin and Jo In Sung are romcom MVPs. Hyo Jin is one of my favorites, and has had the good fortune of starring with some truly amazing male leads (including my kdrama baes So Ji Sub & Gong Yoo), but this match manages to rank high even on that list. In the beginning their banter went over my head, but I instantly loved watching them together. The way Jo In Sung would look and smile at her, to their tit for tat moments, made me swoon and cheer them on! Their chemistry was palpable, and their love story felt so real. Their flirting, their irrational fights, their struggle with their personal demons, their struggle to figure out how they fit in each other's lives... This drama manages to take a situation that would probably be a true mess in real life, and turn it into one of my favorite KDrama couples. It's also a mature adult relationship, which gave it an intimacy that many other KDrama romances lack. Yes, this story is primarily a love story, but there's also some suspense, a little melodrama, and a hilarious supporting cast. Sung Dong Il and Lee Kwang Soo, at least to me, should be considered main characters. That's how important they are to the story. Watching the four of them in that house was awesome. I love the idea of friends who are like family, and who choose to live supporting each other. It's probably not ethical, but you have to throw all ethics away to enjoy this kind of drama... Hey, "It's ok, it's kdrama". All of the minor characters are also multidimensional, no one is completely good or bad, which makes them feel more realistic and interesting. I also have to mention Do Kyung Soo, who was so good that he broke my heart a few times as Kang Woo. He had his own great chemistry with Jo In Sung, which really made the character work well. Even though I thought the main story was excellent, there were a few things that I didn't love, which stopped me from giving it a perfect score. First, I understood the purpose of the patient stories, and introducing different disorders, but I didn't find them all that interesting. I think some of that is cultural. Some of what triggers the minor (and main) characters just didn't seem like a big deal to me. I could empathize, because the acting was good, but the story line itself still wasn't interesting to me. I did like the overall idea of introducing the disorders specifically, normalizing them like any sickness, and removing the stigma associated with them. It was also not done heavy handedly, which makes it more effective. The other weak spot for me was Soo Kwang and Oh So Nyeo's relationship. They were great in their roles, but I just didn't like their relationship at all. Even though he was adorkable, he kept giving me dirty older dude vibes. Eventually they grew on me enough for me not to not be annoyed by their scenes, but I still never quite rooted for them. Part of the beauty of the show is that all the love relationships are messy, so it still worked, and that is a large part of the shows appeal. The direction, I think, was perfect. There are certain scenes that are so well done visually that they were haunting. It's the same writer director team as "Padam Padam..." , and the "That Winter, the Wind Blows", so I am definitely a fan. The music was great, and not your normal kdrama ost, but worked really well to enhance the story telling. So would I watch this again? Duh! I knew what would happen, but I was still just as excited watching. Watching this again, like it was the first time, was like knowing a joke's punchline and still finding it completely hilarious. There are psychological elements, and a some twists, but knowing them doesn't ruin the show. I also totally missed the characters at the end, so that's enough of a reason alone to rewatch. Overall, I think this is a must see drama. It's about how beautiful love can be in spite of major complications, and I loved it from the intriguing first episode to the awesome last episode. If you are in a difficult relationship, it may trigger some feelings, which may trigger some Dramnesia... (which I now suspect was what caused mine lol), but in the end, it's a really inspiring and entertaining story about trying to make relationships with each other work (whether romantic or platonic). If you normally find KDrama romance too cheesy, I think this drama is perfect for you. If you love to squeel at cutesy KDrama romcom moments, I think this drama is perfect for you. If you don't like romance at all, I think this may not be the perfect drama for you, but you should totally watch it anyway. There's a reason why the reviews are so high. I will be adding it to my favorites list now, so I won't be able to forget it again.
