[Quick transmigration + harem romance + female side character rises to the top + Mary Sue + no fixed pairing]
The succubus Jing Hua, asleep for many years, is awakened by System 004.
The System tells her that a bug has appeared in a once-stable small world. After being reborn and transmigrating into it, a wicked woman uses her knowledge of the plot to come between the male and female leads. The story collapses, their fortune is stolen, and countless people's destinies are changed.
Resentment is overflowing in the underworld, and she is urgently needed to set things right.
Jing Hua lazily yawns. “What do you need me to do?”
“You need to enter the small worlds and fulfill the wish-makers' wishes, eliminating their resentment...”
