Zeuse and Demeter had a daughter named Kore. Demeter was very overprotective with her daughter because she didn't want any men around her.
When Kore grew up she grew up as a sweet girl who got the attention of many gods. Demeter had a lot of love for Kore that she decided to keep all men away from her. There was this one boy named Hade that when he saw Kore he fell in love with her at first sight.
Hade wanted to marry Kore so he asked Demeter if he could marry her daughter, Demeter got furious and said that was never going to happen. Hade stole Kore while she was playing ball with her friend because Hade actually wanted to marry Kore but Demeter wouldn't let him.
When Demeter found out that Haden had stolen her daughter she got really mad and decided to get revenge.
Demeter gro revenge by drying up the earth there was no vegetable growing and animals were dying from lack of food. People were begging and crying to Demeter so Thus promised her that she would find a way to get Kore. When Thus found Kore she was already getting married but Hade had given some seeds to Kore so she can forget everything and it was about that point where Hade asked kore who would she want to live with and she said him.
Where do you want to live?
I want to live with you.
Demeter accepted the fact that Kore married Had because Kore would go half months with her and half months with Hade.
