22xx - as well as the other sequels about this robot, "Jack"
Angel Shop - sort of but may not be what you're looking for
Strange Stories - last oneshot
Dear My Doll - maid robots lol
A-I Revolution - teaching the robot turns to romance
Mimosa Salad - this is just a oneshot
Rein Klar - not scanlated (I think?)
The Song of Dreams - not primarily romance but it's implied
Are you ok with BL? Because there's a lot of mild/heavy shounen ai or yaoi with robots.
Edit: There was this beautiful shoujo one-shot I read somewhere in which this girl saved a robot who had been abandoned in the snow and he later returns to thank her in a most unexpected form... Omg it was so sweet! Anyone remember the title?
