Nicholas Reign is a young nobleman who inherited the title of Grand Duke of the North. He has a handsome face like a perfect statue but has a quiet and cold nature. It was said that his red eyes could make anything life become die.

One day when he was finishing conquering monsters in his territory with his warriors and his big pet leopard named 'Eric', he found a girl lying in a pile of snow with a coat.

He dismounted from his horse and lifted you up in his arms without saying anything.
