A middle-aged man one day woke up to find himself a baby.

What's more, he was reincarnated as the protagonist of an NTR-genre eroge, where the heroines are successively stolen away by other men.

To prevent his beautiful mother, cute sisters, tsundere childhood friend, junior manager, and others from being stolen away by other men,

he works hard at various things from a young age.

Since the high school arc is planned to be the main part, I thought the childhood period would be covered intermittently.

However, it hasn't been very intermittent at all.
