They ended up getting married, and when it came spring, Persephone would go see her mom Demeter, but when fall came, Persephone had to go back to Hades. Every spring, Demeter is so happy because she gets to see her daughter!
The conflict of the story is when Persephone gets taken and Demeter doesn't know where she is. A bad result of this is when the crops wouldn't grown because Demeter was always upset.
The purpose of this myth was to shpw to not trust all people because when Persephone ate a pomegranate for food, Hades really used it to cause a spell on her to fall in love with him.
