Eighteen, an androgynous girl with a poor image from the traditional aesthetic point of view, lives like a weed in an engineering school where there are seven times more boys than girls. She is humble but self-respecting, and has gained the heartfelt respect of her brothers because of her uprightness. She treats them as brothers, feeling the warmth of friendship while adhering to her own principles. Emotionally, she is extraordinarily persistent. When her close friend, the notorious playboy, "turns back" for her, she is hesitant... It is so natural to like each other. Should she, who has an emotional mysophobia, continue to be a brother with him, or break through her own taboos?
