As long as Bai Luo plays his role well and steers the overall plot in its predetermined direction, his mission will be considered a success.
First world:
Bai Luo is the honest, spineless husband of the protagonist shou.
The protagonist shou is a born flirt who keeps getting involved with other people. After his honest husband asks for a divorce, he chases him back and goes through hell to win him over.
After a long campaign of relentless pursuit, he becomes the least notable of the protagonist shou's love interests.
Having read the plot, Bai Luo enters the little world full of confidence.
The moment he opens his eyes, he's in the middle of a divorce scene.
The protagonist shou across from him looks angry and resentful, and accuses Bai Luo:
"After all these years, you still haven't learned how to turn people down."
"When you were flirting with those people, did you ever respect me as your actual husband?"
"Let's get divorced. I'm tired."
Bai Luo: Wait! What???
Why is he stealing my plot?
The System promptly appears and forcibly gets the plot back on track: It's okay. As long as you complete certain plot points, like "refusing to give up," the mission can still be saved.
Bai Luo ponders this.
Some time later.
Bai Luo thinks: System, I don't think this situation is right.
The System stubbornly insists: I-it's fine. As long as the overall plot is the same, it's only the roles that have been switched. A-a minor issue.
Second world:
Bai Luo is a scumbag who uses a life debt to force the protagonist shou into becoming his boyfriend.
He's the protagonist shou's inescapable nightmare and shackles.
Gloomy and obsessive, whenever the protagonist shou talks to someone else, he suddenly appears like some spiteful ghost.
As soon as Bai Luo enters the little world, someone locks him in an embrace.
The person holding him is covered in blood, but grips his arm tightly and repeats with obsessive intensity:
"I saved your life. You have to be with me."
"You'll never get away from me for the rest of your life."
Bai Luo: ??? Dude, are you stealing my script again?
"He's a scumbag."
"A creep who uses saving your life to guilt-trip you."
"Bai Luo, if you're willing, I'll take you away."
The protagonist gong has barely said a few words to Bai Luo when an angry, twisted face is already reflected in the glass behind them.
The protagonist shou raises the shining knife in his hand, and when Bai Luo looks at him, he smiles darkly.
He mouths the words: "You're mine, forever."
Third world:
Bai Luo is a rich second-generation heir who throws his weight around.
He forcibly keeps the real young master, who has been living away from home, as his lover.
He becomes the one stain on the protagonist gong's life.
This time, Bai Luo enters the world normally.
He lets out a sigh of relief.
Just as he picks up a glass of wine and goes to find the protagonist gong to get the plot started, a man stops him.
"I know you, young master of the Bai family."
"If you don't want the Bai family to get into trouble and lose your loved ones, become my lover."
"Being with just me would be much better than having to serve a whole group of people."
Nearby, the protagonist gong pretends not to care while waiting for Bai Luo to come over. Seeing this, he crushes the wineglass in his hand, his face cold.
