There’s a type of novel where, in the early stages, the protagonist is always a poor judge of character and gives their heart to the wrong person. Only after being battered and bruised do they finally wake up, kick the scumbag to the curb, and rise to become a winner in both love and career.

This kind of story is commonly known as a “change-the-gong crematorium” novel.

In such novels, besides the main couple, there is another important character who runs through the whole story and cannot be ignored—

the ex-husband scumbag who wronged the protagonist shou.

A huge disaster struck the Space-Time Book Bureau.

An ex-husband NPC in one of the book-worlds awakened self-awareness, patted his butt, and ran off. Before leaving, he even hacked the Bureau’s database, causing the role of “ex-husband” in multiple worlds to go missing, pushing those worlds to the brink of collapse.

The Ex-Husband Roleplaying System “N001” was ordered in at the critical moment. It binds hosts and sends them into endangered worlds to fill in the missing key plot points.

After reading the eye-searing original novels, the forcibly saddled hosts all respond with cold, cutting expressions:

“Are you sure your name isn’t the ‘Cuckold System’?”

The system answers awkwardly:

“…Host, you just need to follow the script and be as much of a scumbag to the male lead as possible. Once the real top gong takes his place, you can retire in glory!”

Host:

“Got it. The scumbag ex-husband deserves a miserable death, but as long as I complete the mission, I get to come back to life looking fabulous.”

Some time later—

the system starts crying like a pig being slaughtered:

“Host, aaaah…! Why is it that all the scumbag plot has already been completed, but the protagonist’s affection for you keeps rising?! Hurry up and divorce him already!”

The host looks down at the protagonist cuddling and acting spoiled in his arms, and says with practiced coldness:

“Let’s divorce.”

Protagonist: “?”

—What kind of nonsense is this guy pulling now?
—So today it’s divorce play?

World 1: Hormonal Illusion

You are a dark, despicable playboy bastard son. As an Alpha, your reputation is already rotten to the core, yet your pheromone compatibility with that proud, arrogant aristocratic Omega is as high as 100%.

The other party’s gland has a fatal defect, leaving him no choice but to enter a marriage alliance with you. After marriage, his cold personality gives way to excessive dependence on your pheromones, and he lets you do whatever you want.

All you know is—

he was once your elder brother’s fiancé, and that alone greatly satisfies your desire for revenge.

So you viciously grab the back of his neck and sneer into his ear:

“Has my brother tasted you like this too?”
