How to Survive as the Duke’s Time-limited Mistress

“If you want to live, make me happy. So much so that rumors spread that I’ve gone mad over a woman.”

In a crazy game with no less than eighty-seven endings,

I possessed Lethe Etimos, the villainess who faces a tragic death in every ending.

It’s unfair enough to wake up in a dungeon with shackles on my limbs, let alone being a death row prisoner!

To survive, Lethe becomes the public mistress of Castor, an ally in the game,

and just when she thought she was enjoying a luxurious life in the Duke’s mansion…

“※If the goal is not achieved within the time limit, the penalty ‘death’ will be given.

▷Success Reward: ???

▷Remaining Time: 4,319 hours 59 minutes 48 seconds”

Due to a damned quest, overnight, my life expectancy has been reduced to half a year.

“Leave the Duke’s mansion.”

“Leave the Duke’s mansion.”

“Leave the Duke’s mansion.”

Sharp warning sounds and bright red warning windows appear incessantly.

The relationship between the two deteriorates to the worst under the system that even controls emotions,

“I’m very curious about what expression your husband would have if he saw you like this.”

The man, who was once affectionate, visits her bedroom every night with a cold gaze…

“Just give up now. You know it as well. That there’s nowhere left to run.”

All she wanted was to live out her life and die in peace.

Can Lethe successfully complete the quest and survive?
