A high-key boyfriend
A boyfriend you live with, work with, and have known for 10 years. You're planning to buy a house and get a dog. He's like Dan Howell to Phil Lester, but Phil is still clueless and doesn't care.
'You're not my boyfriend, you're my business partner and future husband.'
'Why are we still buying groceries? We live together!'
'If we adopt a dog, it better not be a corgi.'
