I love it! The production obviously spent much. The cinematography is that of a movie and each sequence is properly put together. The OST is also great, but I mostly want to hear the full piano version. I like that even though it's a music genre, you don't put musical scenes all the time, just proper timing. The acting is great too, all the actors conveyed proper emotions. Right now, I feel bad for all of them especially Sol, Sun and Piano. These characters have issues of their own. I'm starting to see the selflessness of Sol, he is misunderstood. He obviously put himself in the background and would not even talk if Sun does not want him too. He wants Sun to get the spotlight, it's very clear; Sun does not see his worth, he is too focused on being compared to his brother, not seeing that he gets to do whatever he wants because his brother lets him; Piano is a dreamer and full of passion. I like that she is not afraid to show his feelings but at the same time not being too pushy with Sol and I also like that she frankly told Sun that they can't be together. Right now, I mostly feel bad for Sol and irritated with Sun because of the petty things he does. Can't believe it takes other people for him to realize that whatever Sol does is mostly for him. Just 2 episodes and I'm already seeing each characters depth. I'm looking forward to more episodes. I know that music genre is not popular to the casual viewers but it's obviously more than that. I hope more people can watch it.
