Zeus and Demeter had a daughter called Persephone and every god wanted to be with her. The one that wanted to be with her the most was Hades, but Demeter did not approve of that so Hades decided to kidnap Persephone.
Because Hades had taken her daughter and Zeus didn't tell her she stopped being a goddess and let everything die
No one noticed where Persephone went except for two people, those two people were Zeus and Helios. Zeus decided to not tell Demeter because he did not want to get in a fight with his brother and Helios didn't say anything because it did not involve him
While Zeus was looking for Demeter, Hades was giving Persephone a pomegranate seed. Witch is the devils fruit
Demeter was looking everywhere for her daughter but could not find her then Hecate told her to go talk to the all-seeing sun god Helios. When she did she was weeping and begging for him to tell her something, so Helios caved in and told her that Hades had taken her duaghter.
Stop fighting how about if Hades gats six months with her and you get six months.
When Demeter got furious that her daughter was with the god of the underworld she left her duties of being a goddess and let everything that lived on earth die. She was the goddess of harvest and fertility, so there were no crops and because there were no crops animals died and then humans died.
When Zeus took notice that if everyone on earth dies no one will worship the gods. So Zeus got Hades and Demeter together and got them to talk, but when Hades got the new he used pomegranate seeds to make Persephone believe that she wants to stay with him.
Hades's plan works and Persephone wanted to stay with Hades. Demeter didn't believe it for one second and demanded to know what he did to her, then a fight broke loose. Zeus calmed them down and decided that Persephone would spend six months with Hades and six months with her mother. The six months that Persephone is with Hades are called Autom and Winter the time Demeter gets to see her daughter is Summer and Spring
