Lu Zhiyuan is one of the most senior employees in the Underworld, but a newly hired colleague provokes him, claiming he's never completed a mission.
Lu Zhiyuan is indignant, but it's true. He's also curious about why he has never been assigned a mission.
To redeem himself and secure his standing at work, he once again petitions the Underworld's ruler. To his surprise, this time the ruler agrees and pairs him with an adorable little System.
He swears he'll make that new employee eat their words!
First face-slap: The domineering CEO, who'd dreamed of divorcing him, throws a tantrum and begs his substitute wife not to leave.
Second face-slap: The yandere Demon Venerable agrees to coexist peacefully and withdraw from the human realm, just to soothe his anger.
Third face-slap: The regent, who wants nothing but the world, presents it to him with both hands and kneels before him, begging him not to leave.
After smoothly completing mission after mission and having the time of his life, he suddenly realizes that these NPCs all look a little like a certain ruler.
The ruler says, “Can't I use public funds to date?”
As the truth comes to light and memories surge back, were all those moments from the past real or fake...?
