I didn't watch series while it was airing because I'm not a big fan of shows that are focused on music ?. Despite that I enjoyed this show very much. The OST was surprisingly good, music you can listen to on its own. The show was cute and heartwarming. Ultimately, it is about healing and finding yourself (again). The characters weren't over the top, you can understand why they act the way they do. This series shows you don't always need high heat or a complicated story to make an enjoyable show.
