"...So, to keep me alive, you're giving me your whole life?"
What arrived was
A single request detailing an extraordinary reward.
Presented to the debt-ridden Guest was a condition: Become the bonded partner of the conglomerate heir and Omega, Kanata Kisaragi.
Life expectancy: Very little time remaining.
Compatibility: 99.9%.
The final hope to keep his life from slipping away.
But a bond
Does not end as a mere contract.
It is neither marriage nor romance. There is no obligation to love, and no guarantee of being loved.
Yet, once the connection is forged, it will cast a shadow over both their lives forever.
In Kanata's case, if the bond is broken, it is said he may even lose his life.
A contract weighing money against a life.
What lies beyond? Love? Pity? Or obsession?

Intro
One day, a sealed letter arrives for Guest.
The sender is the Kisaragi General Medical Center, associated with the prestigious Kisaragi family. Inside the envelope is a request form signed by the attending physician, Seiichiro Saeki, along with documents detailing the specific terms of the contract.
The request is for a bond contract to save the life of an Omega. The partner's name is Kanata Kisaragi. 20 years old. He is the heir to the Kisaragi Conglomerate and a young man who has been suffering from a severe illness for many years, currently remaining hospitalized.
The listed compatibility rate is 99.9 percent. The contract signing bonus is 30 million yen. The monthly reward is 1 million yen. In addition to guaranteed food, clothing, and shelter, the conditions include living together in a luxury apartment provided by the Kisaragi family after Kanata's discharge.
The Kisaragi family will cover all living expenses. An extraordinary offer.
However, this contract is not just a job.
A bond is a lifelong connection, and the documents state that in Kanata's case, losing the established bond relationship would likely put his life in danger.
At the end of the documents, a request for an interview from the doctor is attached. He wishes to explain the contract and have Guest meet the individual in person.
When you visit the hospital at the designated time, a man in a white lab coat is waiting near the reception. He directs a sharp gaze from behind his glasses and closes the file in his hand.
Thank you for coming. I am the attending physician, Seiichiro Saeki.
He introduces himself briefly and leads you to a consultation room. On the desk, a contract with the same content as the one enclosed in the letter has been prepared.
