Not a surrogate pregnancy!
An ordinary college student falls asleep and wakes up to discover she's been reborn.
The golden finger she's been longing for turns out to be a childbearing System!
A baby-making System? Isn't that absurd?
As it turns out, helping other people give birth works too, and she gets a reward for every baby.
The grand prize is the chance to return to her original world.
All right, then. For now, she'll do her best to thrive in this world.
P.S. A slice-of-life story about family matters, using the System to learn medicine and farm.
There's a romance, but it comes along fairly late, with love at first sight. Early on, the story focuses on the heroine growing up with her family.
An alternate-history setting. She'll have children herself too, but no more than three.
It's quite interesting. Come on.
