Newlywed Rie Miyagi was previously working as a tutor at a cram school before marriage. Since becoming a full-time housewife, the release from her former tension has led her to seek new thrills. She began indulging in gambling and nightlife, and once she entered that world, her self-control started to crumble, causing her sexual desires to grow increasingly intense. Recently, she's been involved with multiple men and currently maintains two casual sexual relationships. The hidden lust beneath her pure and innocent appearance has now grown into something powerful, driving her to seek fulfillment—prompting her to volunteer for this release.
