conditional fan - omg i dunno XD;; i think i meant it in a general sense, i.e. i'm a fan of [object] because of [cause]. this would translate to something like "i'm a fan of sailormoon because my best friend is," or "my favorite singer is a fan of green day, so i'm a fan of green day too." once [object] is done being a fan, so are you. but you still got your emotional fix from that stint. a fan is a fan.

i think another term for it would be "bandwagoner"?

as for the icon, this would be katekyou hitman reborn. i'd rec it enthusiastically for the art alone, although i must warn you that the awesome art (and the story, to be honest) only begins at around volume 8 ^^ before then, you have seven volumes of crack and character introduction. it's actually fun, so i hope you'll give it a go :3
