Arthur goes about his day normally! That's all he wants, normalcy. However, that all changes when he meets a strange man who turns his world upside down. He didn't think that this new person would have supernatural powers.
During the 13th century, Francis and Arthur knew each other since they were kids. However, their spiteful nature got them in trouble one night when they ran into a witch. The witch cast a spell on them to live forever by the time they were twenty-six unless they found love within each other. However, it's going to take more than just a century and complimenting to Achieve that.
