To be honest, I see a lot of people that are not pleased with this drama, but I totally loved it! It wasn't anything WOW and it wasn't anything Ew, it was a really good drama! just that! The story for me was amazing^^. I love these kind of plots that have to do with Music. The acting was pretty good, nothing is wrong with it, just some times maybe, they were overreacting with their facial expressions I think. but it wasn't bad. it wasn't done a lot. very few times. The soundtracks were supreme! i loved every single OST , especially "I am OK" which was kinda the "main" ost from what I understood! The rewatch value goes to Zero, cause I only find dramas rewatchable when they got some kind of action inside, Well this drama of course doesn't have action xD. so I find it pointless to rewatch it. Maybe some of you may thing that my score is "TOO GOOD" but, I don't find anything weird with the drama. That's why, and its all personal preferences of course so #peace! Reasons i watched this? Hyped with the Gfriend Cover at the beginning xD.
