It's a Korean drama and the beauty of it is its portrayal of relationships no matter what kind. The connection between all the characters is precious and touching. The storyline for a lot of the drama is quite lacking but makes up for it with its powerful ending. Midway it flounders and goes in circles and doesn't make a lot of sense but the characters are EVERYTHING. With this kind of complicated premise, it would have been helpful if they hashed out the “rules” of the personalities a little more. I didn't expect this show to be so funny. But seven personalities in one body can get you into a lot of interesting situations. Can we just give Ji Sung 10 million awards? This guy deserves all the stars. This drama really put this actor through the loops. The characters and challenges that Ji Sung goes through in this drama to create different personalities in really wacky situations is so phenomenal. What an actor. What. An. Actor. Do Hyun Do Hyun is compassionate and gentle. He is at a disadvantage because he doesn't remember what happens when his other personalities are in control. The other personalities do remember and so they make deliberate attempts to confuse Do Hyun in order to be in control of the body. It was very strange to have the one personality leaving video messages for Do Hyun to find when he re-awoke. Also, his other personalities are enemies with himself. Do Hyun takes full responsibility for his actions when he wakes up – the poor fellow! You'd think that after all this time he'd just try and not show his face to the numerous people he's offended but he awkwardly strives to make things right. It was interesting to see Do Hyun take some really active and practical measures to monitor his mental health to stop the personalities from kicking in. He was determined. Shin Se Gi Hello guyliner. This personality is smart and conniving. He knows how to pretend to be Do Hyun. He's the bad boy personality and the bad guy all wrapped up into one. I liked how the drama made a point of Se Gi having to bear the brunt of Do Hyun's unpleasant experiences and how he is the protector. The ongoing fight that Do Hyun has with this character is sinister and intense but also very heart-breaking. Yo Sub Yo Sub was a bit cliché at first but he really brings out a beautiful side of Ri Jin and his character improves. Again, Ji Sung's quiet portrayal of him is intense and effective. Ri Jin She does a lot of yelling. When she's happy she screams, when she's angry, she screams. When she's drunk, she screams. She gets irritated a lot. I preferred her sweet side which is unusual for me. I usually like the ferocity of a heroine but Ri Jin's shining moments were when she was sharing her heart and quietly expressing feelings. That's when she seemed the most genuine. A lot of the times she has so little common sense that it frustrates me. But other times, her psychiatric brain is working just fine and she just has the perfect comebacks. But her dramatic moments seemed like overacting. It was hard to tell if it was just Ri Jin's superficial personality or the actress' weird portrayals of her. Siblings Ri On and Ri Jin are awesome sibs. They're great. It's the cutest. Ri On as a brother is way better than a boring best friend sidekick. He is so brilliant and funny. I really really liked this guy. His comic and tragic side is beautiful. I like that his dark side isn't even part of the main tragedy but it's just as heartbreaking but in a different way. He's just so wrapped up because he loves his sister. And when he turns on the serious badass side? Daaamn. Ki Joon I liked this guy a lot even though he had to play a stereotypical bad guy. But his expression was far from boring. His portrayal of the uptight guy who seems put together but will explode if things don't go his way, is flawless. You know it's a good drama when I've got way too much to say about every character. How amazing is Ri Jin's mother? That compassionate and maternal look on her face is so beautiful.
