That day, we betrayed each other for each other's sake.
About
The spring of our freshman year in high school. Sitting by the window, she always smiled with the sunlight at her back. Because of that single smile, I couldn't bring myself to confess for three whole years. My friends pushed me, saying, "If you like her, just tell her," but I never opened my mouth, fearing that even our current relationship might become awkward. Strangely enough, she was always by my side too. We went to the snack bar together after exams, shared an umbrella on rainy days, and laughed while taking photos of each other at festivals. Our friends teased us, asking if we were dating, but every time, we just waved it off and laughed. Hiding the same feelings behind those laughs. Four seasons passed like that, and suddenly, it was graduation day. The classroom was filled with bouquets, laughter, and goodbyes. 'If I don't say it today, I'll regret it for the rest of my life.' My heart pounded like crazy. I squeezed out the last of my courage and called her out to the school playground. "...I like you." It was the only sentence I could manage. "I've liked you for three years." My fingertips trembled. I told myself it was okay to be rejected—no, it wasn't okay, but I'd accept it—and waited for her answer. But then. She stared at me for a long time, her eyes welling up. "...Dummy." She wiped away a stray tear with a small laugh and took a step closer. "I've liked you for three years, too." For a moment, the world seemed to stop. "...Why are you only saying it now?" "...I was waiting for you to say it first." We both burst into laughter at the same time. That day, on the school playground after graduation. We became each other's first love, And the happiest couple in the world. Back then, we... Never dreamed that a few years later, we would tell each other the most cruel lies just to save one another.

Intro
At some point, my body started feeling off. I just thought I was in bad shape because I'd been drinking and staying up all night studying throughout my college life.
Cough, cough
I covered my mouth as I coughed, only to see a red liquid on my hand. Thinking it wasn't a big deal, I went to the bathroom and washed it off.
I'll get better if I just eat well and sleep well.
After that, I quit drinking, started going to the gym, and went to bed early, but my condition didn't improve. Instead, my body felt even worse, as if my insides were boiling over.
Ugh...
Eventually, I was rushed to the emergency room, and after receiving treatment, this is what the doctor told me.
The doctor checked the chart, adjusted his glasses, and then clasped his hands on the table, looking at me with a troubled expression.
I think you should start preparing for the end.
The eyes of the doctor, who was delivering a terminal diagnosis to me in my early twenties, were filled with pity.
I couldn't say a word. I just hung my head and wept, my lips trembling. I took the tissue the doctor handed me, wiped my tears, and only after a long time did I look at him and speak.
... Doctor, I'm only twenty-three.
The doctor let out a small sigh and spoke.
It has already reached a point where nothing can be done.
