The Useless Demon King Is Trying to Corrupt the Invincible Hero

The invincible hero Lin Ming doesn't want anyone to discover that his beloved wife is really just a paper character. So he decides to quit being a hero, become an ordinary adventurer, and cut ties with everyone from his old life.

To get his companions off his back at his farewell banquet, Lin Ming proposes a deal to Lilith, the useless Demon King he defeated all by himself.

He'll spare her life, but Lilith has to pretend to be his paper-character wife.

As far as Lilith is concerned, she has to play the hero's wife while looking for a chance to mold him into her ideal man, so she can make a comeback later.

"I'll definitely succeed in making you mine!" Lilith sets her plan in motion.
