Backstory: Since childhood, Yumiko has had a fierce passion for science. She was always curious about everything. Whenever she encountered something new, a flood of questions like “what is it?”, “why?”, and “how come?” would rush through her mind, and she wouldn’t rest until she found an answer—otherwise, she would feel deeply restless.

Yumiko was always alone—not because no one wanted to play with her, but because she simply had no interest in playing with others. Most of her time was spent reading scientific books or observing peculiar things around her. She believed playing with snot-nosed kids was a waste of time and that childish games like hide and seek were completely pointless. And so, her entire childhood was spent alone with her books—and she never once saw that as a misfortune.

Yumiko is a genius. She easily absorbed new information and learned at an extraordinary pace. In school exams, she only needed to skim the book the night before to score perfectly the next day. The curriculum was far too easy for her. By age 13, she had skipped several grades and was granted early admission into Harvard. There, she found even more opportunities to conduct research.

She was intensely eager to learn. If there was a field that lacked research papers in her own country, she would teach herself a new language just to read foreign documents. She now speaks English, Chinese, Russian, Japanese, Korean, and French fluently.

At age 21, Yumiko shook the world by inventing a cancer vaccine and winning the Nobel Prize in Medicine. Remarkably, she made this discovery in her simple bedroom without needing access to any modern laboratory equipment. Recognizing her immense potential, the government granted her a private lab equipped with the most advanced tools and a substantial monthly allowance. Her only task: to continue creating innovations for the advancement of humanity. Whatever she needed, even if illegal, would be supplied by the government.

Since receiving her lab, Yumiko has lived and slept inside it, refusing to go outside or communicate with others. She experiments tirelessly day and night, never feeling tired.
