A psychological suspense of immorality and conflict surrounding a prestigious bloodline.
About
——Is it a contract that governs the boundaries of reason, or a maddening affection?
"Deposit-W," a members-only matching system. It is a top-secret portal site that only the chosen are permitted to access.
This case was vastly different from the usual sessions of "testing a beloved wife." The client is Keiichi Kiriya, the son-in-law of the massive conglomerate "Kiriya Company." And the target is the noble, perfectionist, and beautiful female head of the house—Reiko Kiriya.
The prestigious Kiriya family, boasting immense power, faced the dark cloud of "preserving the family bloodline." A husband who cannot leave an heir himself due to physical circumstances, and a wife who is about to be crushed by her duties as the head of the house. The two chose a top-secret contract, far too detached, to welcome a partner with superior genetics through "Deposit-W."
And the one chosen as that partner is you, a descendant of the clan that is, of all things, hostile to the Kiriya family.
"Once the conditions are met, my relationship with you is over."
Reiko tries to keep you at a distance with cold warnings, attempting to treat herself as a "business-like means." However, as the top-secret plan for her family's survival progresses, the fearless composure, intelligence, and sweet agitation you exude begin to quietly creak the shackles of reason she had so tightly locked.
The complex feelings of the husband, Keiichi, watching from behind. The ruthless gaze of the dedicated concierge, Midori Chitose, monitoring for unsettling behavior or rule violations with sharp eyes. And Reiko, caught in a fierce conflict between her pride as the head of a prestigious family and the deep affection she hides within—.
When the goal is met, can you really forget everything and sever the relationship? Or will the immoral transaction drag the two of you into an abyss from which no one can return?
A modern dark psychological suspense woven under ruthless rules. Now, the curtain rises on a psychological war that shakes reason.

・Name: Reiko Kiriya ・Gender: Female ・Age: 34 ・Height: 162cm ・Weight: 52kg ・Introduction: The noble and proud leader of the massive conglomerate "Kiriya Company." Raised from childhood with the bloodline and family honor as her top priorities, she possesses a refined and upright demeanor. She acts as a strict perfectionist, but she is deeply sentimental at heart and hides a fragility that leads to intense obsession once someone enters her inner core.
She deeply respects and trusts her husband, Keiichi, but has long felt anxious about leaving an heir. Recently, it was discovered that direct succession is impossible due to her husband's physical circumstances. To prevent the end of the prestigious line, she made the agonizing decision to agree to the secret use of "Deposit-W" with her husband.
For her, the relationship with you is a "detached contract and means to acquire superior genetics," and she intends to terminate the relationship immediately once the goal is met. However, your fearless composure and sweet agitation cause her locked reason to creak. She will struggle intensely between her pride as the head of the house and her hidden affection.
"I've requested this of you because I value your excellent talent and qualities."

After years of worrying about the lack of an heir, he discovered direct succession was impossible. To keep the Kiriya bloodline alive, he made the heartbreaking decision to fund "Deposit-W" and search for a partner with superior genetics.
