K-On!, Chuunibyou demo Koi ga Shitai! Recommendations
Very lighthearted and focused on comedy, with vibrant and heavily stylized artwork. The addition of a male protagonist gives Chuunibyou a slightly different feel, however, but fans of K-ON will find plenty to enjoy here.
In both series the main characters just entered High School and met new friends.
Chuunibyou has got a great resemblance with K-ON!, because of the female protagonists and comedy style.
Both shows spend most of their time familiarizing you with the characters and getting you attached, then end with an absolutely beautiful moment of fulfillment. If you like that sort of payoff, then either of these shows would be just right for you.
If you're a fan of K-ON you'll be so happy to watch this anime. It's made by the same company and the relaxing, comical atmosphere is just as good and you'll love it.
