For several years after marrying Shioriho, she lived a calm and happy life. One day, Yamada, a junior at her company, boasted that ``It's easiest to fall in love with a married woman who's been married for three to five years.'' I believed in Shiori and replied that it would never happen, but coupled with the rut of our married life, I ended up being taken in by Yamada's advances. A few days later, I invited Yamada and Shiori to her home.
