I possessed the body of an assassin who is the exclusive attendant of the Northern Grand Duchess—the protagonist of a romance fantasy novel.

I have no interest in assassination. To survive under the ill-tempered protagonist, I gaslit her from childhood into believing I was her “secret friend”...

“I have no need for ordinary friends. I already have a secret friend.”

“…It seems you’ve made a new friend lately.”

“Oh my, if it’s a secret friend, seeing each other naked should be fine, shouldn’t it? You’re the one who said there shouldn’t be any secrets between us.”

...It seems I may have overdone the gaslighting.
