Hi guys I'm looking for a Sterek soulmates fic. From what i remember this is a past lives soulmate au. Derek and stiles have found each other every life and been soul mates and in every life they die or get separated some tragic way and they make a promise to always find each other. Its past lives all the way up to the teen wolf verse and stiles has started getting tattoos to represent each life with derek, and he keeps getting them, hoping that derek will remember soon.
I do remember that during all this peter is interested in stiles and has expressed it to stiles, so there is some slight triangle, maybe interest. But peter becomes his confidant and stiles admits he could have fallen for him if Derek hadn't been there first...
I never got to actually finish the fic, it was a WIP when i read it. I do remember that Derek slips one day and admits he had already remembered and then my dog got upset sat on laptop and closed out my windows. Please help i would love to read it again... or, well finish it.
**Found** A friend of mine on Tumblr found it and tagged me in a post,
