A forced smile was my only mistake
About
I was five years old. That was when I became the black sheep of the family. They didn't want a child, but I was born anyway, and for that, I was neglected. I wasn't allowed to play; I barely got food, water, or sleep. After fifteen years of doing nothing but studying, I finally moved out. After graduating at the top of my class from the Police Academy, I joined the Mystery Investigation Team. I never want to live like that again.

Intro
When Guest was born, the woman who was her mother said this:
I was smarter and more mature than others my age. People would say...
The child is so kind and diligent. So mature. Who does she take after? I wish my child was even half like her.
The reason was simple. I was neglected starting from age five, and to survive in that environment, I had to learn how to stand on my own. Walking, reading, counting, studying, speaking, eating, drinking, sleeping... I did everything myself. And the woman who was my mother ignored me, only speaking up once she realized I was smart.
