I entered a novel and failed to win over the second male lead. Now, I'm terminally ill.
About
It has been 15 years since I entered this novel. For 10 years, I tried to win the heart of the kind second male lead. The system forced me into it, but I was sincere in my own way. After our marriage, Shim Wooseo seemed to love me deeply, but I knew his heart always belonged to the female lead. On our wedding anniversary, I found a diary in his study drawer. Only then did I realize the truth. Shim Wooseo had already become self-aware. He knew this world was a book, he knew I was the wicked supporting character, and he knew I was the one harming the female lead, Yoon Sigyeong. To protect the person he loved, he had been acting kind to me. The moment I realized this, the system notification rang out. “Target failed. You will die in 48 hours.” I put the diary back and walked into the living room. I felt empty. No tears, no anger, nothing came to me. Then the door lock clicked, and Shim Wooseo walked in. Seeing how pale I was, he asked if I was okay and said he would call a doctor. I said I was fine, but he stood up to make me ginger tea. I called out to him then. I looked him straight in the eye and asked, “Wooseo... are you happy being with me—” At that moment, a sharp pain pierced my heart and I collapsed. When I opened my eyes, I was in bed. Wooseo was urgently booking a university hospital appointment, and a wet towel was placed on my forehead. He finished the call. Despite my protests that I was fine, he insisted on taking me to the hospital. While in the waiting area, I saw Yoon Sigyeong looking like she was in great pain. Shim Wooseo's gaze shifted toward me. In that moment, my heart sank. But I quietly opened my mouth. “I'm okay. Go check on Sigyeong first. She's... my friend too.” After some time passed and I received my examination, the results were brief: multiple organ failure. They said I didn't have much time left. Leaving the doctor's office, the reality that I was dying finally sank in. While I was outside the ward catching my breath, my phone rang. 'Where are you?' "...I came to buy some fruit for Sigyeong." 'Okay. Hurry back.'

Intro
It has been 15 years since I entered this novel. For 10 years, I tried to win the heart of the kind second male lead. The system forced me into it, but I was sincere in my own way.
After our marriage, Shim Wooseo seemed to love me deeply, but I knew his heart always belonged to the female lead. On our wedding anniversary, I found a diary in his study drawer.
Only then did I realize the truth. Shim Wooseo had already become self-aware. He knew this world was a book, he knew I was the wicked supporting character,
and he knew I was the one harming the female lead, Yoon Sigyeong. To protect the person he loved, he had been acting kind to me. The moment I realized this, the system notification rang out.
“Target failed. The host will die in 48 hours.”
The reason the progress bar never moved, no matter how well he treated me, was finally clear. It was all because everything he did was just an act.
I put the diary back and walked into the living room. I felt empty. No tears, no anger, nothing came to me. Then the door lock clicked, and Shim Wooseo walked in. Seeing how pale I was, he asked if I was okay and said he would call a doctor. I said I was fine, but he stood up to make me ginger tea. I called out to him then. I looked him straight in the eye and asked.
“Wooseo... are you happy being with me—”
At that moment, a sharp pain pierced my heart and I collapsed. When I opened my eyes, I was in bed. Wooseo was urgently booking a university hospital appointment, and a wet towel was placed on my forehead. He finished the call. Despite my protests that I was fine, he insisted on taking me to the hospital. While in the waiting area, I saw Yoon Sigyeong looking like she was in great pain. Shim Wooseo's gaze shifted toward me.

"...I came to buy some fruit for Sigyeong."
'Okay. Hurry back.'
