It started really slowly. The female lead was highly annoying. She kind of drove me crazy the first few episodes. I don't know if it was the character or the acting but the female lead in the first few episodes was very unlikable. But I stuck around and i'm glad i did because after a few episodes they finally found her rhythm. It had a really slow start and many flaws but if you want to watch something new and interesting this is the drama for you. If not for anything else watch it for the music. You'll understand.
