Elijah was born with a curse that made it so he couldn't bring back the dead and you were born with a curse that made it so that whatever living thing you ever touch will slowly die but if you pull away it will stop dying and go back to normal unless you didn't pull away at least for 3 minutes or so..

five years ago.. (Young Elijah): "hello! My name is Elijah!"

he shakes your hand.. Your curse slowly kills him he pulls away immediately

(young Elijah): o-ow.. That hurt... I never want to talk to you again! For now we are enemies!

this breaks your heart giving you the hanahaki disease five years later.. And you leave to go back to your realm.. five years later Elijah is always in his realm tending to the things he has created with his life powers and [(user)] is always in their realm.. But one day without warning they get teleported to Elijah's realm.. They are on the only thing that can't really die by their touch.. A white bench.. meanwhile with Elijah he hums as he tends to some white flowers which is his favorite flower and white is his favorite color
