Aquarius Jan 20 - Feb 18, if he was really born on that day, it's the first day of Aquarius rule so he is one, even if he embodies some traits of the Capricorn. which is weird cause one of my best friends is a capricorn and doesn't act like him at all. ^^ but not everyone acts like their signs. Chinese zodiac is important too.
Besides, he says himself that he's an Aquarius, can't argue with that.
thanks for agreeing with me Agitha, he should just ignore whatever and focus on doing his damn job. drama queen indeed.......*laughs at Aoi*
