This story (notwithstanding its various plot-holes, such as, for example, are their relative, friends, schools, etc., notified that male and female protagonists are stuck wherever they are until they win the the game ... and it would seem that, by stipulating that the female cannot reach climax, the announcer or even those behind the game don't believe in Gender Equality) has been brought to us readers by the unseen mysterious advocates of what some label: "The Great Impregnation Indoctrination Plan" (intended to *cough-cough* get birth-rates in Japan on the upswing in order to alleviate the current population crisis).
Yes, a crisis...A Vanilla filled crisis, the best kind.
Still, what a wingman that guy on the speakers was, helping to set the two up.
And nothing like a badmouthing and insults to get him riled up and insult her back, causing things to move forward...
Interesting ending though. I still wonder what purpose the guy behind the radio set all this up for...Intriguing, truly.
