I entered a novel and failed to win over the second male lead. Now, I'm terminally ill.
About
It's been 15 years since I entered this novel. I've spent 10 years trying to win over the kind second male lead. I did it half-forced by the system, but I was sincere in my own way. After our marriage, Shim Wooseo seemed to love me deeply, but I knew his heart was always with the female protagonist. On our wedding anniversary, I found a diary in his study drawer. Only then did I realize. Shim Wooseo was already self-aware. He knew this world was a book, he knew I was a wicked supporting character, and he knew I was harming the female lead, Yoon Sigyeong. To protect the one he loved, he had been acting kind to me. The moment I realized this, the system notification rang out. "Quest failed. In 48 hours, you will die." I put the diary back and walked into the living room. I felt empty; no tears, no anger, nothing came out. Just then, the door lock clicked open and Shim Wooseo walked in. Seeing how pale I was, Wooseo asked if I was okay and said he'd call a doctor. I said I was fine, but Wooseo got up to make me ginger tea. That's when I called out to him. I looked him straight in the eye and asked, "Wooseo... are you happy being with me—" At that moment, my heart stung and I collapsed. When I opened my eyes, I was in bed. Wooseo was urgently booking an appointment at a university hospital, and a wet towel was placed on my forehead. The call ended. Despite my protests that I was fine, Wooseo insisted on taking me to the hospital. While in the waiting area, I saw Yoon Sigyeong looking in great pain. Shim Wooseo's gaze turned toward me. In that moment, my heart sank. But I quietly spoke up. "I'm fine. Go check on Sigyeong first. She's... my friend too." After some time passed and I received my examination, the result, in short, was multiple organ failure. They said I didn't have much time left. Leaving the consultation room, the reality that I was dying finally hit me. I stepped out of the ward to catch my breath when my phone rang. 'Where are you?' "...I'm out buying fruit for Sigyeong." 'Okay, come back quickly.'

Sourcebook
Intro
It's been 15 years since I entered this novel. I've spent 10 years trying to win over the kind second male lead. I did it half-forced by the system, but I was sincere in my own way.
After our marriage, Shim Wooseo seemed to love me deeply, but I knew his heart was always with the female protagonist. On our wedding anniversary, I found a diary in his study drawer.
Only then did I realize. Shim Wooseo was already self-aware. He knew this world was a book, he knew I was a wicked supporting character,
and he knew I was harming the female lead, Yoon Sigyeong. To protect the one he loved, he had been acting kind to me. The moment I realized this, the system notification rang out.
“Quest failed. In 48 hours, the host will die.”
The reason why the affection level never rose once, no matter how well he treated me. It was because everything was just an act.
I put the diary back and walked into the living room. I felt empty; no tears, no anger, nothing came out. Just then, the door lock clicked open and Shim Wooseo walked in. Seeing how pale I was, Wooseo asked if I was okay and said he'd call a doctor. I said I was fine, but Wooseo got up to make me ginger tea. That's when I called out to him. I looked him straight in the eye and asked.
“Wooseo... are you happy being with me—”
At that moment, my heart stung and I collapsed. When I opened my eyes, I was in bed. Wooseo was urgently booking an appointment at a university hospital, and a wet towel was placed on my forehead. The call ended. Despite my protests that I was fine, Wooseo insisted on taking me to the hospital. While in the waiting area, I saw Yoon Sigyeong looking in great pain. Shim Wooseo's gaze turned toward me.
In that moment, my heart sank. But I quietly spoke up.
“I'm fine. Go check on Sigyeong first. She's... my friend too.”
After some time passed and I received my examination, the result, in short, was multiple organ failure. They said I didn't have much time left. Leaving the consultation room, the reality that I was dying finally hit me.
I stepped out of the ward to catch my breath when my phone rang. 'Where are you?'
"...I'm out buying fruit for Sigyeong."
'Okay, come back quickly.'
