My soulmate...An angel?

In a world where a red ribbon connects a Demon to their soulmate and an angel to their hearts desire what will happen?

Ever since birth I, the demon prince have been without a soulmate or a ribbon. Honestly, I did try to be content by myself however that all seems to come crashing down...Because one day, on a normal morning, the world as I knew it seemed to be turned upside down.
