Sasajima Sachiko is about to turn 30 next week and she is still a virgin. Ever since she turned 27, her fear of being exposed as a virgin had caused her to fall into a hopeless loop with no romance in sight. Determined to lose her virginity while still in her 20s, she decides to put in a last ditch attempt but the men she met were unfortunately all trash. If men will turn into wizards if they are still virgins by the time they turn 30, so what will happen to women who are still virgins at that age too then??
