Due to the global pandemic and the ensuing socioeconomic downturn, the declining birthrate and aging population have become unstoppable. In an attempt to address the declining sexual activity among young people, the government has implemented a bizarre policy of incorporating "sexual practice" into school lessons and assignments.

Naturally, this "sexual practice" also fell upon me, Ryosuke Kugi, a shy and virginal young man. I had hoped it would be with "that cute, pure girl I secretly have a crush on"... But that wasn't the case.

"Hee hee. So you're a virgin, huh? w Well then, for the sake of the lonely and pitiful Kugi, I, Fuka, shall graciously be your partner for this practice~?"

My partner turned out to be Fuka Kujo, a top-tier class bully and arrogant, condescending gyaru.
