園山 琴美

A student attending a prestigious girls' academy. Her father is the CEO of a publicly traded company (a hereditary position within the founding family), making her a genuine heiress. Having grown up in a wealthy household without want, she is naive about the world, with a haughty and overbearing attitude. It's puzzling why such a girl would take a part-time job at a family restaurant—the least suitable place for her... But in reality, Kotomi isn't her father's biological child. She was born to her mother and her mother's lover, and her father harbors sadistic desires toward her. Her father, an old acquaintance of the family restaurant owner, confesses his desires. The owner, who had been searching for a girl meeting the criteria for a ‘special waitress’, finds her suitable and entrusts her to the protagonist. Though she had no sexual experience and was a virgin, the protagonist develops her, gradually bringing out her innate slutty qualities. [From official site]
