Narcissus was a real beauty. He was a hunter, and the son of the river god, Cephissus. He was also full of pride and wasn't kind to those who loved him.
Nemesis noticed his behavior, so he pulled a trick on him. He lured him to the river where Narcissus caught a glimpse at his own reflection. He because fascinated and fell in love. He never wanted to part his reflection, and as he tried to get closer, he drowned.
