Quick Transmigration: The Heroine Wants Her Ex Back? Not a Chance

(System + Female Side Character Takes the Lead + Both Leads Are Sexually Inexperienced + Original Female Lead Portrayed Negatively + Love at First Sight + Immersive)

The world is full of novels with mild plots, and you can't please everyone. If this isn't for you, leave quietly and don't flame the author. Note: Please switch off your brain while reading.

The worlds vary in length. I write without a draft, so even I don't know how things will turn out.

There are many male leads who die because the female lead hurts them or drags them into trouble. Their deaths are just there to help her see the scumbag's true colors, be reborn, slap him in the face, and win the male lead back.

When the female lead wants to get back together, the female side characters who love the male lead refuse to put up with it and unite to appeal to the System Bureau. He Naiyi, a Host of a conquest System, decides to take on their cases. She brings her System along to these little worlds, where she wins over the male leads and stops them from ending up with the female leads, helping the female side characters take their place...

World One: A brooding, puppy-like CEO and his late brother's girlfriend

(Sister-in-law, open the door. I'm home.)

World Two: An Immortal Venerable and his mortal fiancée

(Just a mere mortal? Tsk... You're quite something.)

World Three: A pampered substitute princess

(A substitute? Who's ever seen one prettier and more doted on than the real thing?)

World Four: A princess sent from a foreign land for a political marriage

Starting with this world, I'm off to earn some grievance money. I didn't write this one well, so feel free to skip it.

(Though she's a hostage, she's so beautiful and delicate.)

World Five: A blind saintess of the Wu tribe and an emperor with amnesia

(How dare a little slave with amnesia defy his master?)

World Six: An unloved empress and a regent with power over the court

World Seven: A fake heiress who takes another's place in a Republican-era marriage and a young marshal

(Young Marshal, get down on your knees, hold me, and don't leave. Isn't having me enough?)

World Eight: A prince and his stepmother

I will inherit everything my father owns, including you, my queen...
