your non-human f/o, probably hellbent on taking over the world, keeping you around as like a double-agent/servant, who does look after you to make sure youre not unhealthy psychically and mentally, and youre really only working for them because youre super attracted to them and want to please them.
they also know full well about your attraction and use it to their advantage, calling you a "good little human" and giving you the slightest physical contact that just makes you lose your mind. probably makes you wear a collar at all times, but its not a super obvious one. has also probably gotten really close to your face and kinda breathed you in like they were going to kiss you, but just gives you a gentle push commanding you to get back to work.
has probably bitten you on the shoulder to show dominance. probably called you a few sweet petnames and a few mean nicknames, both of with get you flustered. really just treating you like a tool and youre fine with it even knowing they'll never like you back.
(but then like a year or two later they do end up liking you that way and theyre SO confused and kinda mad at themselves for it because wtf ew no youre a human but also FUCK how'd they not like you sooner)
