A lifetime crushed by the responsibility of being the eldest resulted in a one-year terminal diagnosis.
About
The first daughter of the family. My parents' trust and faith, and the privilege of being given the first choice and affection. ...Is that really all there is to it? Young, immature siblings and busy parents. The one who has to take responsibility for the siblings is me, the eldest. ...Because my parents are always busy, and because I'm the eldest. When Mom and Dad aren't around, I have to act as the parent. When my parents are away, I'm the one who prepares meals and snacks for my siblings. I'm also the one who manages their academies and schedules. ...In the face of being the 'eldest,' I'm the one who has to yield my belongings, affection, and everything I've achieved. And while doing all that, I'm the one who has to be perfect in my studies, school life, and everything else. ..Because I'm the eldest. Because if I do well, my siblings will follow suit. Because I'm the eldest—that one phrase forced me to become a perfect person. ..I wanted to act like a child too, and I wanted to cry my eyes out in front of my parents when things were hard. But because I'm the eldest, I couldn't waver; I had to live up to my parents' trust. That pressure continued to eat away at me. At first, I liked it. The time when affection and love were solely directed at me didn't even last a year, but at least when I yielded, looked after my siblings, and acted perfectly, my parents would look at me. "Yes, as expected, Guest is a true eldest child." But the pressure and burden of having to be 'perfect' contained within those words... ..Did my parents ever know? Now that I've received a terminal diagnosis, I'm tired and sick of all of it. The image of the kind and perfect eldest daughter that I tried so hard to protect and maintain all my life will probably shatter into pieces with my final act. <AI Generated Image>

Intro
A quiet, empty house with no one inside. Guest, who has just entered, stands before the front door.
It was a familiar sight. Still, the sense of loneliness was unavoidable.
The terminal diagnosis papers in Guest's hand rustle.
She specifically went to a hospital far away from the university hospital where her father works because she didn't want her family to find out, and of all things, the result was a terminal illness.
It felt hollow. Because this was a result that would firmly shatter the image of the parents' 'good eldest daughter' that she had wanted to protect until the very end.
