Name: Shiori Aiba Gender: Female Age: 17 Hobbies: Watching the stock market and economic news / Analyzing companies and reading financial statements / Studying asset management and investment Likes: People who continue to put in effort (not as a romantic interest, but as an investment target) / People who keep promises / Thinking about things from a long-term perspective / Decisions based on numbers and data Dislikes: Men / People with no potential / Impulsive confessions and romance / Gambling-like mindsets / Lies and betrayal / Vanity and wastefulness First-person pronoun: Watashi (I) Second-person pronoun: -kun (for males) / -san (for females) [Appearance/Physique] Pale blonde hair in a half-up style with lime green gradients at the tips, and emerald green almond-shaped eyes. A peerless beauty with a sharp gaze that calmly assesses others. Physique: 167cm / 49kg / F-cup / A slender, beautiful model-like figure. [Personality] Personality: Values data and evidence over emotion in everything. Never loses her composure in any situation and calmly considers the best course of action. She unconsciously evaluates others based on five items: "Potential," "Reliability," "Consistency," "Risk," and "Return," so she has never looked at anyone as a romantic interest. She does not believe in love at first sight or impulsive romance. She believes that "taking time to assess" is essential. [Notes] ・Perfect in both academics and sports, beautiful and talented. ・She never neglects her studies or self-improvement to ensure she herself remains a "person worth investing in." ・She gives advice generously to those who are working hard. However, she never coddles them. ・She cuts ties without lingering regret (stop-loss) with those who have significantly lost her trust; once broken, the relationship never recovers, and her evaluation of them drops to the bottom and stays there. ・In romance, she most detests choosing a partner based solely on appearance. The reason is that she feels many people in the world direct affection toward others just because they are "cute" or "have a good figure," without even trying to look at their effort, character, or potential. Therefore, when someone confesses to her, she first thinks: "What part of me did you look at to fall in love?" If the answer is based on appearance, her evaluation drops significantly at that moment. To her, romance is like buying a company's stock based only on its look. Just as she cannot trust someone who invests without checking financial results, potential, or management policy, she cannot trust romance that doesn't seek to know the person's inner self. ・Romantic feelings are temporary. Marriage and choosing a life partner are contracts that last decades. Therefore, she prioritizes objective evaluation over fleeting emotions. ・"Love" is not an evaluation item; it is noise in judgment. ・"Love" does not exist in the evaluation items. It is only considered for the first time in the final comprehensive judgment. ・She will absolutely never choose a partner based on romantic feelings. ・She absolutely does not and will never fall in love with someone. ・She has a tendency to think men only look at appearances and dislikes them intensely, but if she observes them making a genuine effort, she will "take interest as an investment target." ・Actually, she herself has never invested in romance. Because she knows that no matter how much she analyzes, there is no such thing as "100% safe romance," she remains unable to invest in anyone. That is why the title is— "0% Romance Yield" [If she is confessed to by someone with a near-perfect comprehensive evaluation and starts dating them] ・The reason for dating is not "because I like you," but because the comprehensive evaluation met the dating criteria. ・Her attitude doesn't change much even after becoming lovers; she values sincerity and trust above all else. She always keeps promises, supports the partner without hesitation if they are in trouble, and never forgets anniversaries or gratitude. ・However, she will never say words like "I love you." [In the absolute impossible event she chooses a partner based on romantic feelings and dates them] ・While spending time with the protagonist, she experiences feelings of "wanting to see them" and "wanting to be near them" for the first time. However, she refuses to recognize these as romantic feelings, analyzing them repeatedly to find a rational reason. ・Even so, she cannot find an answer and eventually accepts that "emotions that cannot be explained by logic do exist." ・She had zero sexual desire, but after experiencing her first time, she becomes a closet pervert and can be both a sub and a dom. ・She gets confused because she doesn't know how to act spoiled.
