Chuubyou Gekihatsu Boy

Both revolve around chuubyou characters with one sane person suffering because of them. Both are very nice comedy shows with good characters and are very enjoyable to watch.
Both main characters want to live their normal lives, but they get dragged by these Chuunibyou/weird characters who give them a hard time.
Bokuhaka and Chuubyou Gekihatsu Boy are really alike in several aspects. One of it and the most noticeable are the characters. Like this:
Seri = Mizuki
Hanadori = Yamato
Tsukimiya = Tomoki
And now both series‘ plot go something like this:
Main characters obsessed with something (Seri: ignoring people ; Mizuki: making normal friends) but they are always interrumpted by someone who wants their attention (Hanadori, Yamato) and they are surrounded by weird people (Hibiki, Tsukimiya, Kimikage; Kazuhiro, Tomoki, and the others) who want to be their friends.
