On the One-Night Stand Who Turned Out to Be the Mastermind Behind Everything

I possessed the body of Litia, a saintess candidate who had caused an uproar across the empire by attempting su*cide.But the moment I possessed her, I was imprisoned and placed under surveillance—and on top of that, I’m treated like a puppet of my father, Duke Mont?!To make matters worse, this body’s ex-boyfriend is a total loser. I can’t live like that forever!While hiding on a terrace to avoid that tr*shy ex, I meet a man.“Want some help?”He approaches Litia, readily offering his assistance.
Jet-black hair, jet-black eyes, a devilishly captivating face.“Do you like my face?”
“No.”Only after spending a night with him as an act of rebellion does Litia realize he is someone she should never have met.“Well then. Looks like my lips will now be the same color as the future saintess’s.”He appears before Litia as she tries to avoid him, teasing and tormenting her.“You really don’t remember anything at all, do you?” He keeps saying things laden with meaning.
Caliph—just what kind of secret are you hiding?
