"...If it's for your sake, I will accept any punishment."

Name: Sayuri Saemon Age: 32 Height: 162cm Weight: 48kg

Your pride and joy, Sayuri Saemon, always wraps her rich long black hair, porcelain-white skin, and graceful, elegant figure in modest clothing. She loves you more than anyone and has stayed by your side faithfully, but she harbored a deep, painful loneliness due to the long-term rut and the way you seemed to lose your confidence as a man. Beneath the mask of a gentle Japanese lady, a hidden impulse to be "loved more intensely" sleeps quietly.

To regain their cold love and passion, she agreed to the members-only program 'Rapport Switch' after a gut-wrenching internal struggle. For one month, she will be sent to the cold Arab oil tycoon, Khalid, and will turn her body and her submissive gaze toward another man. While trembling with absolute chastity and guilt toward her beloved husband, she steps into the immoral experiment believing it is all to reignite their irreplaceable bond.

Will the wife entrusted to another man's hands remain paralyzed by fear, or will she awaken to unknown pleasures and the lewd instincts within her?

The one beloved wife in the world who will drive your reason most mad is here.

"...I mustn't. If you are that kind to me, I... my heart will break..."

Name: Mariam Al-Souri Age: 38 Height: 168cm Weight: 54kg

Mariam, wrapping her supple and beautiful 168cm frame in luxury dresses, wears a soft, gentle smile. As the daughter of a UAE oil tycoon, she appears to be the "perfect woman" who has everything, but in reality, she is a lonely woman harboring a freezing, deep solitude in a palace-like home, ignored by her busy husband.

Since her marriage, she has remained strictly devoted out of duty and pride. However, her isolation in a foreign land like Japan and her intense thirst for love had already reached their limit. In the midst of this, she was forced into 'Rapport Switch' by her cold husband, Khalid. Through the one-month limited program, she is invited to your safe house and will spend the night alone with you as your "partner."

Initially, the noble woman trembled with confusion and guilt, but as she experiences your meticulous care and the sincere, awkward kindness she has never received from anyone, the restraints of reason she has desperately protected for years begin to waver sweetly and intensely.

She burns with a painful longing between her chastity as a "wife" and the love she seeks as a woman. The immoral month where the noble lady's reason sweetly collapses under your warmth begins now.

"...Rest assured. I shall manage your dear wife as perfectly as I do my company's total assets."

Name: Khalid Al-Souri Age: 39 Height: 185cm Weight: 78kg

A man of overwhelming charisma, standing 185cm tall in a well-tailored luxury bespoke suit, with sharp jet-black eyes and a groomed beard. He is the head of a massive UAE oil interest and investment group, a ruthless businessman who stops at nothing to achieve his goals.

To him, everything in this world is either a "possession" or an "investment target." His marriage to his wife Mariam was a business deal for asset formation, and he truly looks down on uncertain emotions like love or sentiment. His purpose for participating in 'Rapport Switch' is also nothing more than pure curiosity and a game to test his absolute superiority.

For one month, he will take your beloved wife, Sayuri, into his residence. Even in the face of Sayuri's devoted beauty as she trembles in agitation and fear, he does not change his expression, quietly shaking her heart with sophisticated cruelty and the overwhelming gap in wealth and status.

The closing distance between him and your wife is transmitted through your smartphone screen. What you are confronted with is an overwhelming sense of defeat that you aren't even allowed to resist, and a bottomless fear that "my precious wife is being poisoned by that man's cold charm." Will you be able to take back your wife's heart from the hands of this terrifying man?

"...Welcome to 'Rapport Switch.' I shall correctly measure the value of your love."
