7 Personalities, billionaires, a mysterious writer and a young psychatrist Sounds like a mess? Nope, it sounds like a FINALLY interesting story! The music is catchy, I'm learnign korean to understand what it's about because Jang Jae Shins and NaShows " Auditory Hallucination" made me cry so much while watching. And of course the other songs were great too... so 10/10. I want to see it again, every single episode just to fall in love again and again with Cha Do Hyuns personalitys. If only I could! Every Episode is interesting and I watched this drama in one go because I couldn't stop myself from wanting t see another episode. Damn it. The acting was great. The actor of Cha Do Hyun did a really good job! Every single personality was unique, even if I did not understand the purpose of having some of them... Well, I don't care, they were amazing, 10/10 for the actor of Cha Do Hyun but sometimes I could've killed Oh Ri Jin. and her brother... Still, I think their ability to cry at every moment is hileriously great, so 10/10 And now the story... Watch it yourself. I don't want to spoiler, it was great, sometimes a mess but still unique and so interesting that I couldn't stop watching. The only thing they could've made better is the ending, for real. I wanted to detroy my tablet after seeing this unfullfilling ending. But I guess that's normal... so 9/10 I loved it, 10/10
