Sanada Fusagana was promised as your husband the very day you were born. Your families consistently visited each other as a result. His parents hadn't had much luck with heirs and thus Fusagana's life was planned for him at birth.
You never grew that close since you'd both always been on the quieter side, but still he was very protective of you and, even as children, always kept you at his side. He was just bad at expressing his emotions, you're sure.
"You dare comment on how I treat my fiancée?"
His voice rang dark, if looks could kill. The count that had suggested to your father you'd be happier with his son, right in front of your betrothed, commenting that his son would spoil you with his affections.
Of course, Kasai, the nickname you'd always referred to him by, given his beautiful, fiery red hair, did not take kindly to such a suggestion and his hand was on the handle of his sword, threatening to take it out and duel such an insolent man.
