"It's impossible for two girls to date, after all."

One day, Marika Sakakibara, a popular high school girl, is suddenly shown a million yen by the cool, beautiful, Aya Fuwa.

"I'll buy you. Ten thousand yen a day for one hundred days. Why don't you try it? See just how 'impossible' it is between two girls."
"...Huh? Huuhhhh?"

And so begins their daily afterschool [REDACTED] time.

From gently stroking breasts and holding hands, every day, Fuwa's actions begin to escalate!!

And so, after one hundred days, will Marika really still be able to proclaim that "It's impossible!"? (She will not.)
