The Ex-Girlfriend Side Character's HE Guide [Quick Transmigration]

[Looking for favorites for my similar quick transmigration novel, The Former Girlfriend's Self-Rescue Guide (Quick Transmigration)!]

Jing Zhao is an employee in the quick transmigration division. Her job is to play the male lead's first love in each small world.

As the character destined to be sacrificed, she plays roles that are either spoiled and hypocritical or greedy and materialistic, forming a stark contrast with the genuinely kind heroine who will appear by the male lead's side in the future.

The heroine heals the wounds the male lead suffers at Jing Zhao's hands, leading to a healing happy ending.

However, the Main God tells Jing Zhao that the male leads she has tormented are so deeply hurt that they no longer believe in love. The employees in the true-love division have all failed, unable to heal them, and every small world has collapsed and been destroyed...

Jing Zhao is forced to go back and clean up the messes she left behind, one by one.

(Complete) World One: spoiled heiress x poor, innocent top student (she seduces the top student, then shatters his sincere heart and wantonly tramples and humiliates him)

Jing Zhao before going back: It was just a bet. It's really fun watching our top student fall in love!

Jing Zhao after going back: ...

(Complete) World Two: black-hearted woman scientist x puppy-like experimental subject (when the apocalypse arrives, her boyfriend awakens a powerful ability, and the greedy scientist wants him for herself)

Jing Zhao before going back: Love? Why talk about love when the apocalypse is here? It's no match for an ability like yours. Don't worry, as long as you cooperate, the pain will be over soon.

Jing Zhao after going back: ...

(Complete) World Three: spoiled, high-maintenance childhood friend and pretty face x top-tier star and childhood sweetheart (the pretty face enters show business and abandons the actor for better opportunities)
