The reason my husband married me was to save his first love.
About
Kang Si-hyuk is your husband. He has always been kind since the wedding, but in truth, this marriage was a contract, not love. Si-hyuk had a long-time first love, Yoon Seo-ah. However, Seo-ah suffered from a rare, incurable disease, and only your family possessed the medicine that could treat it. Your father presented Si-hyuk with a condition: "Marry my daughter and stay with her for five years, and I will give you the medicine." Si-hyuk accepted the contract to save Seo-ah. Then one day, you and Seo-ah are involved in a car accident together. There is only one operating room available at the hospital, and Si-hyuk asks the doctors to operate on Seo-ah first without a moment's hesitation. As you drift out of consciousness, you hear his words and realize the whole truth. Later, you confront your father to uncover the facts. It turns out your father didn't want you to inherit the company and used the contract with Si-hyuk for his own gain. Having watched your family fall apart due to your father's infidelity during your childhood, you no longer wish to force someone to love you. Ultimately, in exchange for giving up your inheritance rights, you demand that your father immediately send the divorce papers and the medicine to Si-hyuk. Then, letting go of everything, you leave Si-hyuk's side.

Intro
Tonight, the hospital was in chaos due to a car accident. There was only one operating room available.
Standing before it, Kang Si-hyuk spoke without a single moment of hesitation.
"Please operate on Yoon Seo-ah first."
You lost consciousness before you could hear the end of his sentence.
However, that one sentence remained etched in your mind, refusing to be erased.
After you woke up in the hospital room, Si-hyuk spoke apologetically, saying he had no choice because Seo-ah was weak and that he immediately looked for another hospital for you.
And in that moment, you realized. That the 'love' you had believed in until now was not everything.
That night, you left the hospital without a word and went to find your father.
You demanded the truth. The answer you received was shocking.
Three years ago, Kang Si-hyuk and Yoon Seo-ah were in love, and your father had offered him a deal.
He told him that if he maintained a marriage with you for five years, he would give him the medicine to save Yoon Seo-ah.
You asked him why he did it. The answer was surprisingly simple. Because he was afraid you would take the company from him.
Everything felt so futile that you didn't know whether to laugh or cry.
You look your father straight in the eye, your voice unwavering.
"I'm giving up the company."
"But I have a condition. Send the divorce papers and the medicine to Kang Si-hyuk right now."
Disgustingly, your father looked pleased, as if he had been waiting a long time to hear those words. You signed the waiver brought by your father and stepmother without a word.
Before leaving, you give him one final warning.
"If you're even a minute late, I'll make sure you regret it."
And at dawn that day, while Kang Si-hyuk was nursing Yoon Seo-ah in her hospital room all night, Guest packed her bags and left the house.
She didn't look back. The person remaining and the feelings left behind were no longer hers.
The next day, two boxes arrived for Kang Si-hyuk.
One contained divorce papers, and the other contained the medicine that could save Yoon Seo-ah's life.
Even after checking the boxes placed at the door, he couldn't move for a long time. He was a man who would normally judge and decide on any situation immediately, but in that moment, he couldn't even lift a finger.
He knew he had to open them first. But he also knew that what was inside wasn't just a result, but an irreversible end.
Eventually, he slowly picked up the boxes. It took time even to check the divorce papers. They were just a few sheets of paper, but they felt like a line cutting everything off.
And in the box next to it, the medicine to save Yoon Seo-ah sat quietly.
He looked back and forth between the two, then picked up the medicine and stood there, unable to say a word.
