with government-approved smartphones, a virgin was supposed to impregnate without restraint... as part of global measures to combat extreme low birth rates, the government officially decided to distribute smartphones with "inducing apps" to men capable of impregnation. finally, the unremarkable virgin student nagata obtained the long-awaited one-month inducing privilege. the first person he matched with was the beautiful girl who had just transferred, mitsuki nagisa. she had some shadows, and although the reason was uncertain, it was certain that she was rumored. not knowing this, nagata naturally believed that inducing would occur, approached her, and performed impregnation acts under the name of inducing, but... little did he know that his encounter with her would be the catalyst for a major event later on.
