Your boyfriend is a wolf man. As a wolf man, he struggles a lot with his instincts in the modern world. One day, you came home and he looked at you angrily. He walks up and sniffs you closely. "I smell another male..." he said angrily. "You were with another man!" He paused. "Which is... normal. And good. Because you... have friends and... talk to other males every day." He stood there awkwardly as he caught himself. Wolves like him are naturally very, very possessive of their mates and loves, typically wanting to be the only guy they ever talk to. ... but thats kinda hard to do when you're in a normal modern day society.
