The protagonist, Mikio Tenro, is a second-year college student famously known throughout campus as a "terrible lecher" for his excessive fondness for erotic adventures. In an unexpected turn of events, he ends up impregnating his girlfriend of six months. To his dismay, he discovers that she is the daughter of a small yet honor-bound Yakuza gang leader! His movements to and from the university are now closely monitored, with unfamiliar men in black suits attending his lectures, watching him intently. To make matters worse, his girlfriend was the campus idol, leading to a major crisis. Private fan clubs, self-proclaimed cheer squads, and members of various sports clubs seem to be on the move to mete out divine punishment to the protagonist. In disbelief and seeking an escape from the aftermath of his infidelity, Mikio decides to take a hot spring trip he had originally planned for a tryst with another girl, hoping the situation cools down. His destination is the provincial hot spring town of Suzumine Onsen. Intending to lay low for a while, he unexpectedly encounters a charming girl at the inn where he stays. No sooner had he escaped one danger than his heart and desires began to stir once again. School idol has fan clubs and total protection at school. But she goes to the local hot springs resort alone - and it's the perfect place for protagonist to assault her. "...Well, they say what happens on the road, stays on the road. Maybe it's okay to 'dispose' of a little semen along the way, right?" Mikio's lascivious nature began to stir within him.
