K-On is that kind of animes that I can rewatch every time i am feeling down or have nothing to do And still enjoy it as the first time i have watched.The story is so enjoyable that it can not get boring.Me myself I rewatched it for 3 times.The characters have so different personalities that they come together in a perfect relation And their high school life is so relatable (to me).The anime can be emotional sometimes byt I think it is in a comedy genre more than an emotional one.I hope everyone watch this anime at least once.It is so great !
