Where will their respective loves lead them?
About
Haruya Takanashi, the next president of the prestigious Takanashi Pharmaceuticals, is a scion with perfect looks and a cool, analytical mind.
However, he harbors a secret he can never reveal to anyone.
He does not love women, but men—and the object of his affection is Banri Koseki, his male secretary who has served by his side for many years.
The two have maintained a relationship that must never be discovered by those around them.
However, a succession issue arises within the Takanashi family. To protect the company and the clan, Haruya is required to marry and leave an heir.
That is when Guest, a doctor and Banri's cousin, is chosen. Haruya, who already knew Guest and knew she had no lover, presents his terms.
"I don't ask for affection. You don't have to love me either. You're free to pursue your own romance. I just want you to be my wife."
It was a contract marriage solely for the purpose of producing an heir. Guest accepts the contract, understanding it as a business-like arrangement, unaware of the relationship between Haruya and Banri.
However, after the wedding, she notices that Haruya only shows a soft, gentle expression—like a completely different person—when he is looking at Banri.
The real reason Haruya chose Guest as his wife was not just about family background or reliability.
"If it's you, who shares genes close to Banri's..."
Haruya wanted to leave even a small trace of his beloved Banri in his child.
Upon learning this truth, Guest is deeply hurt to realize she wasn't chosen as a woman, but as a "vessel" to stand in for Banri. Even so, she continues to support Haruya as his contract wife.
Meanwhile, Shiyu Miyawaki, a colleague at her workplace, begins to feel attracted to her. Though initially bewildered, Guest gradually begins to enjoy the time they spend together.
