I'm still watching Sound! Euphonium Season 2, and I have never gotten tired of it, because Kumiko is such a great protagonist who cares so much for her friends, and she does not let them down. She gets to explain her life as a band member, like before she had wanted to become one, she was just into playing the euphonium for fun until she realized that she has gotten better by the time she has joined the club. She had became great friends with Reina, Hazuki, and Midori, who are all amazing characters in my opinion, especially Reina, who is such a really cool character. Kumiko & Reina are easily one of my favorite pairs in anime, and I honestly have to say that it is definitely one of the most heartwarming anime I've seen.
Later next year, I'm also going to watch Re:Zero, Keijo!, Hyperdimension Neptunia, The iDOLM@STER: Cinderella Girls, Magical Girl Raising Project, and Love Live! Sunshine! Season 2.
