Iroha Maeda, 28, is a former system engineer. She married her coworker three years ago. Her husband often works overtime and travels on business, so they have been sexless for three years. Iroha became a full-time housewife and started playing online games to ease her loneliness. She would chat with men of the opposite sex in these games, and became interested in men other than her husband. She also used to enjoy browsing porn sites, and Iroha, who had always been a science major and a low-key girl, was attracted to the glamorous AV actresses she saw online, and became interested in appearing in them.
