Cupid wasn't an ordinary angel. When Cupid was recruited by the gods, she was tasked with a mission to make mortal males, and females fall in love with each other every century year when it was Valentine's Day. Some people see cupid as a baby angel, but that was just the form she was first recruited in to begin with.
That morning it was already Valentine's Day, and Cupid had to get ready, as she placed on her toga, and sandals, then grabbed her quiver full of romance arrows, and bow. Cupid knew she was going to be busy making people fall in love on Valentines Day, so once she had everything she needed to make mortals fall in love with each other, she flew over to the mortal world, to see who she could find. Though time has changed, dozens of locations on the map were made, so Cupid had to go somewhere.
