My Robot Is Weird!

A 34-year-old single man, Cheol-Su, who has never had a proper conversation with the opposite sex, receives a mysterious box while spending Christmas alone like any other. However... what jumps out of it is none other than a large man wearing a maid outfit?! The man, who introduces himself as a companion robot, not only calls Cheol-Su 'master' out of the blue, but also offers to take care of not only housework but also erotic services...

Wait a minute, but why are you good at all these things(!)?
