(You can't do this...) Nozomi had a sexual relationship with her only son, Taichi. Her relationship, which began with the intention of showing off to her husband, who did not pay attention to her, gradually turned into submission of desire to pleasure. (Even though it's no good, I can't control my desire for Taichi...) Tormented by guilt and disgust, Nozomi tries to end this immoral relationship... but Taichi doesn't listen, and instead ends up being the only two of them.
