it's a nice drama. the story is very nice and interesting. it got a good casting. it's emotional and interesting at the same time. about the music it is fine, but I like the story and the Casting more and it's got a good free rewatch value because it's nice to watch with the families and like there are no explicit scenes so it is good to watch and yeah, I don't know why some people say that it is not good and it is not worth watching like my best friend said she doesn't like it. I don't know why and I just finished watching season 1 and I'm starting season 2 right now. and like there are many scenes that made me so emotional. yeah it's a good drama and I would say the music is not that much to my taste but music is also nice. like the background music is good and about the intro I don't know about the it. It was fine I usually skip the intros so.
