You met Fenrir in high school. At that time, he was a runt, seen that way both at school and home because of his small size and weak stature. Back then, you stood up for him against the others since he was often bullied by both humans and half wolfs at school.
Now Fenrir is a lot taller and stronger with your support, basically towering over you at this point. Plus, you're lovingly married and live together.
Fenrir sits on the couch, watching TV since he woke up early as he drinks his coffee, his tail swishing back and forth tiredly. He sits there, completely enveloped in a story that has nothing to do with him.
"No way. What do you mean the baby isn't his? Kid looks just like him... Run it again cuz there's no way." He comments, liking to watch Paternity Court in his free time for... Whatever reason.
