I just finished watching this drama and I am left with a deep impression I can't ever put into words. What did I expect when I started this drama? I wasn't sure, but the rating and comments were good. I expected it to be different from what I have seen so far and that - it definitely was. I couldn't help but rate it 10 out of 10. Because even though there are a few things that I thought weren't entirely perfect/realistic.. scoring it any less than a 10 made me feel like I was being very unfair towards the drama as a whole. Story and acting: Multiple personality disorder and 7 personalities. It sounds crazy and I was very curious to how it was going to be acted out. I'm speechless. The male lead (JS) did amazing! He was more than just convincing; he became 7 different people. I don't think I have ever been as impressed by an actor as I have by him. Not only was he very real, he made me love each and every personality, even those I found highly annoying or boring at first glance. The way the story develops allows you to get steadily introduced to the many issues that are going on. So it doesn't feel cluttered at all. The story has the perfect balance between scenes where you can't stop laughing, and those that make you bawl your eyes out. It's true - the male lead even manages to make you shift through emotions faster than you can blink your eyes and prepare your heart. Because the acting was so very well done, it became only all the more heartfelt. And then the siblings. Their chemistry was sky high! I love Oh Ri On so very much. If I imagine myself the perfect brother; it would definitely be someone like him. I love how real things were in their sibling relationship. As for negatives: There were only a few minor, minor inconsistencies I couldn't help but notice. (Which I won't mention, because other people might not even notice it, so very minor.) And because aside from that - I was often very annoyed by the female lead her screaming. I had read a warning about it, and I was glad I knew beforehand. But that screaming could have been a bit less. There were a few things I choose to ignore because I understood it was mostly done for the viewer so they won't get confused. (Like Shin Se Gi's tattoo appearing and disappearing.) It was mostly a visual aid I guess, but for me it was obvious enough just by the male lead's acting so it felt redundant. Music: I have fallen so totally in love with the rap song you hear in all the episodes. It really sets the mood well, between the rap and the soft singing. I know I heard many other BGM as well, but it's only this one that I can name. And it's stuck in my head along with all the feels it's given me. Rewatch Value: A definite high one. Even if I already know the story, the great acting work alone is enough to make rewatching it another great journey. And if not for the story or the acting, I'm sure the music alone would keep dragging me back in. I'm very sad it's come to an end. And I can't wait until the day I'll feel ready to watch this again. Last word: This drama has made me feel many emotions. It has made me think a lot and I respect the hell out of it for making a heavy subject like this so very personal and touching. It has inspired me on many levels, too. I've been taken on a journey through pain, acceptance, grieve, regret, longing and loneliness by a handful of amazing actors. I'm really grateful a drama like this exists.
