Zhou Chen, the dream guy of the gay world, died in a car accident. He thought that was the end of him, but instead he got bound to a Childbearing System and sent to various fictional worlds as the protagonist's love interest, where he had to reach a happy ending with scum tops and complete repair missions.
Zhou Chen: "A Childbearing System?"
The Childbearing System was quite frank: "That's right, Host. As a beginner, you get one perk: you can make a wish, and our administration will grant it."
Zhou Chen: "Oh. Then I want the scum tops to get pregnant and have the babies. I mean, why should it matter who gives birth?"
The Childbearing System froze for three seconds, then Zhou Chen convinced it. "All right."
World One: The Demon Lord, who was supposed to have lovers on both arms and flirt with everyone, has octuplets and begs me not to leave.
As the protagonist's love interest, you were your master's pride and joy, the most promising young cultivator of a prestigious sect. Then the Demon Lord forced himself on you. He was a womanizer and only wanted to have some fun, but you took it seriously, gave him your whole heart, and were abandoned, becoming the laughingstock of the cultivation world.
Zhou Chen: "What is wrong with him?"
After the Demon Lord seduced him, Zhou Chen coaxed him into trying the bottom position, then walked away after a night of passion. Five months later, the Demon Lord, eyes bloodshot, clutched his belly. "What did you... ugh... do to me?"
Zhou Chen replied calmly, "It was just for fun. Don't tell me the Demon Lord took it seriously?"
World Two: The playboy son-in-law Long Aotian, who was supposed to have countless women and live without restraint, has twins in three years and begs me to love him again.
As the protagonist's love interest, you were the devoted fiance in a son-in-law story. Long Aotian used your family's resources and influence to take over your family, while you became the head wife of his harem of three thousand.
Zhou Chen: "What is wrong with him?"
After meeting Long Aotian, Zhou Chen immediately dragged him off to karaoke and told him that a son-in-law shouldn't be so vain, and that staying home to care for his husband and raise children was the right way to live.
When Long Aotian accused him of acting like a son-in-law, Zhou Chen answered confidently, "What's wrong with being the proper husband?"
World Three: The unfaithful, amoral playboy who was supposed to fight for the right to have a third child begs me to be kinder to him.
World Four: The older brother in a forbidden step-sibling romance, who was supposed to be a substitute in a tragic love story, is heavily pregnant and begs me to look at him more.
A melodramatic story, a self-indulgent top-perspective romance.
Theme: Be brave and save the desperate through love
