From what I know of cupids is that they were made from the Greek goddess Aphrodite. She used these little angels to spread love throughout humanity or "the mortals". The cupids specific job is to create couples they think is the ones that will turn out to be true love. Now the cupids job is very simple they find a not-yet couple, they aim with their bow/crossbow and shoot both of them in the butt and BAM...! there in love... just... like... that... I mean in an instant two people could be fighting, next thing you know you have a arrow in your buttocks and you are practically head over heels for the person.
