At first, I only wanted to watch this because it was showing on TV and my best friend said it's a good drama. So, I tried it. It wasn't very eye-catching in the first three episodes, it was boring but then I started to like it as they grow older. I dont know why I didn't like it at first, I might have been 'not paying attention' so I rewatched it from 2nd episode and so on, I love it. If you're serious enough, you'll love it. Especially when MGY and SW grew up into adults. I think the best acting here was of SW, I love her acting, she has her cute side and the evil side. MGY here is rather half evil but inside she cares. I understand her character, the feelings and emotions were expressed well by the cast so I love it. The chemistry between MGY and the first guy is like, meh. I don't want them together, sorry BUT that was only at first. They have like 80% chemistry so it was okay. The songs are daebak! Sung by awesome singers! But I wouldn't watch it again. When it's a bit of a sad drama, I don't think I'd want to watch it again. But overall I give this a 9/10! Great plot, great cast, great music.
