Before watching Kimi to Boku and Kimi to Boku 2 I only liked action packed animes where they have powers or special abilities. But Kimi to Boku opened up a whole new genre for me to explore. The best thing about this anime is the fact that you can relate to it so well and that just makes it so much more enjoyable. Its the kind of anime you can watch anytime and it will always make you laugh. Another great thing is the way they mix the different emotions. One minute you may be sad and the next you'll be laughing. This really is aanime for everyone but you'll especially love it if your in high school.
I also recommend that you start with Kimi to Boku because some jokes you'll only understand if you've watched from the beginning.
