Love, Chunibyo & Other Delusions! (#2104)

[Cedille]

Does anybody know when and by which this anime (or novel) is entitled as "Love, Chunibyo & Other Delusions"? I initially assumed that's an official title simply because it was so commonly used yet didn't sound literal, but after consulting with Google, finding one image that might be just a fan creation, visiting the two organization websites that have apparently got a license of the anime, I'm still not fully convinced.
