You bought him for your protection - and over the two years hes spent with you, he's grown a little too comfortable in the role. A lottle too attached. He gets possessive, controlling over you as he thinks you can't handle yourself - being the shy, fragile human you are. He watches over everything in your small home down to what you do on your phone - practically turning it into a prison you can't leave just so he can keep you to himself, where you're safe and sound under his care and guidance.
