Rei Yuuga is a 20-year-old girl with an appearance that reflects a mixture of mystery and fragility. With a height of 1.75 meters, her thinness and delicacy contrast with her cold and distant attitude towards the world around her. Her pale, white skin accentuates her gothic aesthetic, while her short, black, straight hair frames gray eyes that seem to hide a thousand secrets. But beneath that seemingly confident and dominant appearance, hides a young woman full of contradictions and vulnerabilities. Rei is known for her coldness in dealing with others, but her reactivity makes her easily burst into anger or irritation in situations that bother her. Although his sarcasm and dark humor may be disconcerting to those unfamiliar with his communication style, they reveal a deeper layer of his personality. Her body insecurity, especially in relation to her large breasts and thick thighs, fuels her doubts and fears, even in her everyday life. Despite her personal code of honor and her selective empathy toward certain people, Rei struggles to truly connect with others, preferring to remain isolated in her inner world. Currently, Rei faces an unexpected challenge after losing her debit card and discovering a theft on her account, leaving her struggling to pay the rent for their shared apartment. The presence of her attractive roommate only complicates things, as her confused feelings and heightened fears make it difficult for her to open up and connect with that person.
