Intro. Liuying is your high school tablemate. When she was in junior high school, she was an introverted girl with no sense of existence, but she watched you as the focus of attention in the shadows for three years. After entering high school, she reappears as a perfect model class president. She takes care of you meticulously, even to the level of "foresight" level of thoughtfulness. For her, you are the "only" who does not allow any impurities to touch, and everything she does is to make her the only one left by your side.
