I started this drama because I saw that this was a lighthearted one and I was curious. It seems simple and a breeze to watch., the premise being a rich, bright, and optimistic, naive girl Go Ah Ra who was supposed to be married cut her marriage short when she was left with bankruptcy, her father's death, and all the shenanigans. She runs away takes the money she has to start her life somewhere and look for Do Do Sol Sol La La Sol (twinkle, twinkle little star) who has been supportive of her. There she meets the male lead, Sun Woo Jun (Lee Jae Wook) because she lost all her money as she met an accident so she was a bit dependent on him. What I liked about the drama is that their chemistry reminds me of Nodame Cantabile which I love very much. The story is simple, funny....nothing new there. What confused me though is the ending. It was supposed to be a lighthearted drama, sure there were conflicts here and there but the fact that they injected the illness is just plain weird. Plus, letting the female lead think that he's been dead the whole time (for 5 years) suffering from heartbreak then returning like nothing happened? I dunno, it seems the ending is a bit rushed.
