I just finished watching this drama a couple hours ago and I have to say it was really really good (: I agree with the other reviews when they say this drama isn't boring and has you on the edge of your seat. It's a roller coaster ride of emotion throughout the whole show. I've never come across a show filled up with so much hate and betrayal. I don't think I've hated a character as much as I did the step mother, who I felt myself not liking more and more as I watched each episode. In the beginning you have Eun Sung who comes back from studying abroad in America and her bag winds up getting switched with Hwan. As the story takes off from there you have these 2 characters continuously running into each other. She and her brother get kicked out by her stepmother, and not long after she loses her brother, Eun-Woo who is autistic. Majority of the show she's looking for him. While trying to make money she finds and starts to take care of this grandmother who's lost her memory. I don't want to say too much more, as I'd be giving away the story. Each episode had me guessing at what would happen next, and of course it leaves you hanging so you have to watch the next episode. This show made me cry, laugh, angry, but happy. Then you have the love triangles. It really is filled with a lot of drama and confliction, but that's what made it so good.

The acting in this show, well like the title it was Brilliant! You can really feel for the characters while watching it. I dunno how to describe it, but the acting was realistic. This was the first show I watched with Lee Seung Ki and Han Hyo Joo, and I plan on watching more dramas with them. And whoever played the step mom should've got an award. I hated her character but her acting was really good. Seung Mi's character... I liked her in the beginning but you feel her falling under pressure as the events continue. Her character was played really well, you could feel how hard she wanted to keep what was hers (or what she felt was hers). Jun Sae's character... I liked him. I felt bad for him later on in the story, he is a good guy. I'm glad at how the story ended, though.

As for the music...I liked it. The music played it's part and I liked a lot of the songs played throughout the show.

Will I rewatch this drama? Probably not anytime soon (too many dramas I wanna watch). Maybe a couple years from now I'll rewatch it. 28 episodes is a lot to get through (almost 3O hours total), but I think that watching this show was worth it.

Overall: Definitely worth watching. The story is really good, indeed like Cinderella in ways (evil step mom, step sister, "Prince Charming"). It makes you think about what money does to people. I'd have to count this as one of my favorites now (: And I loved Lee Seung Ki as Hwan haha, but that's my personal opinion
