Love, Chunibyo & Other Delusions (2012)

It focuses on a high school freshman Yuuta Togashi, who once suffered from a 'chuunibyou syndrome' i.e. an overly self-conscious middle schooler. Now he wants to bury this embarrassing past of his and to begin a new life in high school-all in vain. He meets his old friend that knows about the old Yuuta and he now tries to get rid of that shameful part in his life. However, everything is not that easy as it might seem.
