DLDSS-505 I left my wife with a friend who's been single for 32 years and keeps saying "I'm not interested in women," and she came back after he'd had sex with her 11 times without sleep or rest. - Rin Yoda

Rin is in her first year of marriage and living a happy life with her husband, Makoto. One day, Makoto unexpectedly runs into his friend, Haneda. Haneda has never shown any interest in women and has never had a girlfriend, so Makoto wonders, "Even seeing someone as cute as Rin doesn't pique his interest?" Driven by this curiosity, he sends Rin to take care of Haneda, who has fallen ill with a cold... But Rin doesn't come back. The next morning, he realizes his mind has been shattered, and he rushes out the front door, feeling uneasy.
