AFF has over 130k of topics in the romance tag alone. And when you think of romance, what else do you think of? Cupid. Ah, Cupid and his arrows... that's right, arrows. Did you know that he has two arrows? One for desire, and one for aversion. Read it carefully, it's not love arrow, it's desire arrow. There is a different between Love and Desire. Desire is when you want something really bad, even at first sight. Love is something build upon. You can't love someone at first sight. The correct phrase should be 'desire at first sight'.

Cupid's other arrow is an aversion arrow, if one is hit with that arrow, they only have desire to flee. And Cupid can use both arrows to play a sinister game of love, an example with Apollo and Daphne.

"Cupid carries two kinds of arrows, one with a sharp golden point, and the other with a blunt tip of lead. A person wounded by the golden arrow is filled with uncontrollable desire, but the one struck by the lead feels aversion and desires only to flee. The use of these arrows is described by the Latin poet Ovid in the first book of his Metamorphoses. When Apollo taunts Cupid as the lesser archer, Cupid shoots him with the golden arrow, but strikes the object of his desire, the nymph Daphne, with the lead. Trapped by Apollo's unwanted advances, Daphne prays to her father, the river god Peneus, who turns her into a laurel, the tree sacred to Apollo. It is the first of several unsuccessful or tragic love affairs for Apollo." - Wikipedia

Now you can use Cupid as a sinister god in your story and not always the one shooting "love" arrows.
