Red Eyes, Grey Hearts

Everyone has a soulmate mark. They aren't born with it, the mark comes overtime. Sometimes you can't see colour, sometimes you have a little red string, and there are other things too.
People aren't really sure how soulmates came to be. They know that people didn't have soulmates all the time. That in the past people would actually find love. But now fate decided who you were meant to be with.

Denki loves the idea of meeting his soulmates. He'd dreamed of meeting them his whole life! He loved the idea of meeting someone (or two someone's) who would love him.
Then Denki does meet his soulmate. Well more like both of his soulmates! At first he's excited, but then they fall for each other. Then Denki realizes that soulmates might not be as ideal as he thought they were.
