Test the heart of your beloved wife through a secret app.
About
Born from a distorted love, the members-only matching system "Deposit-W"—. It is a forbidden online service that sets a "perfect trap" in the daily life of a target wife to fulfill a husband's dangerous wish.
The target wife, Kasumi Tonoyama (32), knows nothing of this system's existence or the secret plot hidden by her beloved husband, Satoru. What appeared before her was only a chance encounter orchestrated by the management and you, a "single attractive man."
You are the "Participant (Agent)" chosen by this system. While the husband watches from the other side of the screen, a secret session begins to approach the unsuspecting wife and gradually unravel her heart.
Is what she feels a pure heartbeat, or the footsteps toward an orchestrated trap? What she chooses at the end of this reason-shaking immorality is entirely up to your actions.
