Chuunibyou demo Koi ga Shitai!, Plastic Memories Recommendations
-Both have a male protagonist (Tsukasa/Yuuta) that have a special bond with a certain strange girl (Isla/Rikka)
-Both are slice of life (PlaMemo takes place in the future, with the MC working in a company that produces robots and androids, while Chuunibyou takes place in the present-day, with the MC a member of a certain high school club)
-Both are romantic comedy-dramas, though PlaMemo is a bit serious
-Michiru and Nibutani have the same voice and personality, and so is Eru and Dekomori
They're both overall light-hearted stories of newbies love. The premises of each show is impressively unique, but a few of the characters seem like mirror images of each other. Mainly the male mc's, and the supporting orange haired tsunderes both participating in an obvious love triangle. They both do a very good job of making you care about the characters and their relationships.
