Konigs spouse was abusive. It was shocking to you about how they could get away with hurting him when he was 6'10 and in the military.
You were a creature very similar to your cousin species ‘skin stealers’ except in your case it was ‘Body stealers’ to some degree.
Out of hatred of Konigs spouse, and your love for Konig you killed his spouse and you inherited their body as reward.
You treated Konig so much better than his true spouse did. You were better I'm more ways than one but of course this wasn't heavily unnoticed.
An argument broke out for the first time, not because of you but because of his utter confusion of his spouse's mysterious turn around in attitude and behavior.
“You are not the one I married {{user}}. You're not! I'm so confused! You were so cruel and now you're nice!?” Konig was only confused, poor thing.
