I'm Ayumi, 29 years old, still living as a married woman. My husband is four years older than me. When we first met, he was just starting out as a novelist, with a decent income. He was kind, masculine, and the first man I ever had sex with. That experience remains vividly exciting even now. But things have changed—my husband's work has dried up, and he's struggling to find a new path. Then there's him... younger than me, yet already successful in the nightlife industry. The other day, he approached me on the street, inviting me to work at his club. Ever since that offer reached me, something deep inside has started to tremble.
