I based the idea for this story from a TV series Vampire Diaries, if you've seen it, great, if you haven't you aren't really missing much.
I only own the dopplegängers and the plot, nothing else. I also do not really own Allen's dopplegänger, I just gave him a different body other than Allen's.
I know many people have done Yullen soulmates, but this is completely different, maybe.
In this world, it is believed that you have to meet a person who looks exactly like you before you are 20, otherwise you will never meet your soulmate. As soon as you meet your dopplegänger, a word will appear on your arm. This word is the last thing your soulmate will say to you before your first kiss together.
Allen Walker, the white haired 21 year old with no memory of his childhood meets his childhood best friend for the "first" time.
Yuu Kanda, the 24 year old stoic, bluenette who has no dopplegänger, sees his childhood best friend for the first time after 14 years.
What happens when Kanda finds out Allen does not remember his childhood?
Very much OOC Komui and somewhat OOC Kanda
