What's with the Fetish for the Cannon-Fodder Second Male Lead? [Quick Transmigration]

[I don't think this is very good, so I'm planning to take it down. I'll refund everyone.]

Cai Cha is chosen to become the second male lead in a book, the one who always gets cheated on. His poverty, cowardice, and incompetence mean he can never hold on to his lover's heart.

Cai Cha says it's no big deal. "Everyone gets cheated on sometime..."

He has already decided to lie flat and hopes the awful couple will get together soon. So why are they fixated on him?

World One: The Despised Phoenix Man

System: [Your husband, the CEO, is capable and handsome. Before long, he'll fall for a young and beautiful male college student.]

He has already said he doesn't mind, but his friends insist on standing up for him. They take him to confront the "other man" and demand that he let off some steam.

To placate his well-meaning friends, he raises his hand high, then gently lowers it, planning to put on a little show and leave it at that. But just as he lowers his hand, the "other man" suddenly brushes past his face, his warm lips touching Cai Cha's palm.

As luck would have it, the CEO husband suddenly appears in the alley.

He looks at the college student Cai Cha has "slapped," then at his husband, whose face has turned dark.

Why does the CEO husband look so furious, as if he's the one who's been cheated on?

World Two: The Godson Forced to Give Up His Love

System: [You have no ability of your own. If you hadn't taken a big shot as your godfather, you would never have managed to get married. But not long after the wedding, your wife saw through your cowardice and incompetence. She wants a divorce so she can become your godfather's lover.]

Cai Cha loses a fortune in a business deal and goes to his godfather for help.

This is one of the novel's most important plot points: his godfather is supposed to demand that he trade his wife for money.

But his godfather lifts his chin between two fingers, scrutinizing his pitifully pale face, and slowly says, "Don't want your wife to suffer? Trade yourself instead."

Cai Cha blinks. "?"

Who? Who?

World Three: The Despised Husband Who Shared His Hardships

System: [You are the husband who shared the hardships of the junior disciple in a cultivation novel. Your junior disciple is talented and clever, while you have not a trace of spiritual roots and cannot join a sect. You can only wait for him to return after achieving immortality in a little village at the foot of the mountain. But while you wait, the Immortal Venerable secretly falls in love with your junior disciple.]

P.S. 1. I want to control the pacing and avoid padding things out without realizing it, so some chapters will be on the short side.

Theme: Treat people sincerely, work hard, and hope to turn things around when all seems lost
