my 8 soulmates

In the world I'm living in are a phenomenon called "soulmates". The first historical evidence was in the late 1890th. At the beginning it was pretty unusual to have one, but nowadays one third of the population got one. You know it when you turn 18. In the second you lived your 18th year on this earth a mole, kind of a tattoo, will show itself on your body. The scientist don't know until today how this works or because of which rules the moles appear on a particular part on your body. But it is for sure, that you and your soulmates do get the same motive. The motive could be everything, a butterfly, a number or a word. The magic happens when you look into the eyes of your soulmate, your body recognises your significant other, almost every couple reacts in a different way. There could be a spark you see in his eyes, or a crucial pain in your heart, everything is possible. You both are going to feel the same in that exact moment your eyes connect. And after this moment there will be your soulmates name next to your mole.
