After transmigrating into the body of a duke's son, Leo finds himself in the torture chamber of a demon castle, captured by the demon army.
To tempt Leo into falling to depravity, the demon army's succubus interrogator sends a series of women into his room: a cool and aloof elf princess dressed in revealing clothes, a sweet and silly dwarf princess, a wild orc princess, and a holy saintess of light.
Faced with the succubus interrogator's sinister intentions, Leo decides to lie flat and immediately resolves to be a virtuous man who is less than a beast.
That is, until the imposing Demon Queen arrives at the torture chamber wearing black stockings...
Leo smiles. "He's my dad. You think wearing black stockings will make me betray him? No way!"
"You'll have to sweeten the deal. You need to wear fishnets to interrogate me."
The Demon Queen sneers. "Cut the nonsense. I'm here to play mahjong with you."
Leo: Huh?!
"I put on three pounds eating at your place, and all you learned by secretly watching was how to play mahjong?"
