ADN-803 Midsummer, sweat-drenched confinement and training in a sealed room. The complete, step-by-step account of a married woman driven to madness after being repeatedly violated almost every day for two years. Ayaha Natsume.

Ayaha was living a happy, ordinary life with her husband and her son, who had just started his first job. Meanwhile, Toyama—a close friend of her son’s from his student days—harbored romantic feelings for Ayaha. Even as job hunting kept the two young men apart and prevented him from seeing her, his affection did not fade; instead, it twisted into an obsessive fixation. Finally, Toyama went to see Ayaha, determined to make her his own. Without a moment’s warning, Ayaha’s peaceful daily life came to an abrupt end.
