The protagonist lost both his parents, so he is being raised by an institution in the country,
all the while suppressing his desire to be pampered and spoiled.
One day, he hears rumors of a forest spring where "you can meet lots of mommies".
Like an open invitation, he is attracted to the spring.
As he arrives, he is shrouded in light, and before he realizes it, he is whisked off to a strange world...!
He wants to return, but it seems nurturing monster girls are in his way.
If he gives into them, relinquishing himself, surely there will be no going back.
He'll have to decide what it is he truly wants...
