pilot falling asleep in her mech, cuddling the robot girl avatar of the mech itself
i vaguely remember reading a bit of this trashy isekai LN online where someone got reincarnated as the AI of a mech that was very much not supposed to be sentient, and i think wound up getting a crush on her pilot

i also remember seeing some manga that was like "guy is a mech pilot in a war, war ends, somehow mech is given a cute girl avatar and goes to see him, they fall in love and get married" and i was like "oh this is cute, maybe i'll read despite it being het"

and then there was a thing about her wanting to be a 'real human' and UGH

give me the opposite. mech somehow becomes sentient, winds up in a cute doll-like body, and her pilot winds up so enamored that she (or maybe he ) realizes she wants to be a robot girl too
