Two married individuals who met at a drinking party cross the line and form a new relationship. Fearing exposure through exchanged contact information, the woman suggests continuing their affair without using cell phones. Bound by this agreement, they meet every week on a fixed day for dates and maintain their physical relationship. By avoiding smartphones, they achieve a perfect affair with no evidence left behind, embracing the analog inconvenience. Though their means of expressing feelings are limited, they grow increasingly closer through these constraints.
