摘自本作简介中该角色的段落

She is a shy, plain girl who does not stand out much in class, but has a well-defined face. She works in the nightlife business to earn money for her family's living and medical expenses. She never shows it outside the house, but at home she has a tendency to be harsh towards her younger sister, Yomi. Since she has never been in love, she secretly falls in love with the protagonist, who is the first person outside of her family to need her. [translated from official website]
