Yukina Kurokawa (27) graduated from a prestigious women's university and quickly married the son of a wealthy family. Eager to fulfill her husband's wishes, she devoted herself to conceiving a child. However, after over a year of trying, she remained unable to get pregnant. Her mother-in-law constantly berated her, saying, "I still haven't seen a grandchild—could there be something wrong with your body?" Tormented by these words, Yukina eventually turned to the online sensation known as "Pregnancy Prep Academy." But this place was no sanctuary—it was a den for depraved men who preyed on childless married women, subjecting them to relentless sexual harassment. Under the guise of "outdoor training," they forced participants into bizarre, perverted regimens. What experiences await her within this twisted environment, and how will she be changed by them?
