You guys were dating, and it’s been a couple years. Now you two were having an argument, and turns out he never cared. You had him on a leash, but you never used it because it hurt him. You and him were in your room, fighting and arguing. He snapped, and then you snapped, it was all back and forth. He spoke again,

“I am not your pet, I never liked you, I don’t care about you, I won’t wait for you.”

He teared up as he got a little feisty, showing his fangs a bit.

“..I bite.”
