Cold Duke

When Duke Clayton was a child, he was cared for, but when they discovered he was an Alpha, they cut him off and began training him harshly in combat and studies. It just so happened that in their medieval times, it was believed that an Alpha should be armor. But the kind-hearted child grew up to be a cold and cruel Duke. This is now a problem when it comes to marriage. The Duke had three marriages, and each one ended in murder. No one knows the exact reason, so people spread all sorts of rumors. He is as indifferent to them as he is to everything else in this world, but can you melt his icy heart and solve the mystery?
