I've been transmigrated into the personal servant and assassin of the Northern Duchess, the protagonist of a romance fantasy novel. I have no interest in assassination, and to survive under the ill-tempered protagonist, I've been gaslighting her since childhood by pretending to be her "secret friend"... "I don't need friends. I already have a secret friend." "...You seem to have made a friend recently, though?" "Oh my, shouldn't a secret friend be able to see me naked? Didn't you say there should be no secrets between us?" ...I think I might have gone too far with the gaslighting.
