Chuunibyou demo Koi ga Shitai!, Yahari Ore no Seishun Love Comedy wa Machigatteiru. Recommendations
Slice-of-Life, School, and Drama. Well thought-out stories. Though Chuunibyou tend to lean toward the side of romance, and have more comedy. Both offer unique perspectives on growing up, and have done a virtually flawless job of it.
both anime has a romantic/comedy genre
both protagonists have similar personality
both protagonist want to live how they think is normal both had eighth grade syndrome in the past chuunibyou centers around the eighth grade syndrome as the main part of the story but Yahari Ore no Seishun does not
The main characters in both of these anime are extremely relatable, although in slightly different ways. Hikkigaya from Yahari hates his youth, and Yuuta hates his 8th grade youth. They both end up in a club they didn't want to join and are forced to face their "youth." They key reason why these two anime are so great is because of their relatability, comedy, and romance, so if you liked Chuunibyou, Yahari is a must-see.
Both of these series deal without likeable outcasts coming to terms with themselves and the world around them, Chuunibyou is a more romance focused series, whereas Yahari is more about the characters internal developments.
Though if you enjoyed one, you will definitely enjoy the other!
