When Death Awaits

Ok, so I saw this idea on Pinterest. This is exactly what it says on the pin.
"I have this idea in my head
So say everyone really does have soulmates. And if your soulmate dies before you meet them, they become kind of like your "guardian angel." Like they want you to live a really long great life, so they take care of you and protect you as a ghost or something, because their life was so short. And it's really kind of sad because they really want to be with you but they can't, so they wait until you can join them when your ready."
I repined it so if you have Pinterest or know someone who does and you want to check it out, my name on there is AHS_Freak and the board is When Death Awaits-Story Idea (Wattpad) Also, the cover for this book is the picture for the pin I saw.
Oh and I read this pin and jumped on the idea so it's going to take at least a week or two for planning so just hang in there, my *imaginary* audience…
