After Becoming the Second Male Lead in a Sweet Romance (Slow Transmigration)

The gong is the main character.

Every sweet-romance world has a spare male second lead who ends up with nothing. And so, a truly scummy-man System was born.

System: Our motto is, "I'd rather betray the world than let the world betray me!"

1. Sick, evil, beautiful, powerful male lead shou Su Lian x handsome, desireless, laid-back, lazy-dog gong Rong Yuan

Rong Yuan had no ambition. Then one day, he was forcibly bound to a System and quickly transmigrated into a book as a poor, dominant Enigma. After a genetic match, he became the canary of the protagonist gong, Alpha Su Lian. In other words, they got married.

System: "You're the devoted male second lead. To avenge your murder, we'll take his place, kill him, seize his fortune, and reach the pinnacle of life! Love is the least reliable thing there is. Only money and fame won't betray us. Got it?"

Rong Yuan, who just wanted to lie flat: ...

Later, imprisoned Rong Yuan: "Wasn't lying flat what I said I wanted? What do I do now?"

System: ...

2. Wolfish, wild, dim-witted gong Fang Yue x short-tempered, powerful patron shou Xu Zeyan

Fang Yue was a star. With no money or influence, he was framed and killed. After transmigrating into a book one day, his personality changed completely. In other words, he'd stopped caring.

System: "See that patron?"

Fang Yue: "I see him."

System: "You're the devoted male second lead now. You know how to get revenge, right?"

Fang Yue: "Got it. If he pays, I'm happy to be his thoughtful little substitute or whatever."

Xu Zeyan: "Can we talk about our feelings?"

Fang Yue: "...Sorry, but the gold-digger business doesn't cover that."

System: "That's why you're my best Host!"

Other worlds to be decided. One main couple per world. 1v1, happy ending.

Theme: The simple life is the truest one.
