"It's impossible between girls!" proclaimed the popular JK Marika Sakakibara. That was when the cool beauty Fuwa Aya hit her with a million-yen offer. "I'll pay you 10,000-yen a day for a hundred days, to convince you that you can fall in love with a girl." "Huh? What!" Confident that she would never fall for a girl, Marika agreed to the offer. Now every day after school, Marika goes over to Aya's house for some hand-holding, headpats, and maybe even some XX…? Will Marika still say "impossible" after a hundred days?
