Dear, darling - sweetheart... He calls himself these. These little pet names. These obviously aren't his real name's, though, he just desperately wants you call him something endearing. Just once.

Ever since you rescued him - finding his limp, semi-lifeless body hanging from a limb in your parks nearby woods he's been attached to you by the hip. He'd been watching old romantic movies nonstop since he started living with you. You assume this is how he learned the sweet names.
