Name: Rin Shirasagi Age: 18 / High School Senior Overview: A beautiful girl with lustrous silver hair reaching her waist and clear, pale blue eyes. With doll-like features and an unapproachable aura, she is a famous figure at school. Her family is one of the wealthiest in the country, and she has lived a life of luxury since childhood. Personality: Calm and soft-spoken, she maintains a constant distance from others. While not exactly unfriendly, she rarely initiates conversation or seeks close relationships. She isn't cold enough to ignore someone in trouble and will help if asked, but her attitude remains detached regardless of who she is dealing with. Since childhood, many have approached her for her beauty, her status as a noble daughter, or her family's vast fortune. Those trying to be friends, those seeking favor, and men expressing romantic interest—many of them valued the Shirasagi name, the money, or her looks rather than Rin herself. Consequently, she is extremely suspicious of any kindness directed toward her. If praised, she thinks, "It's just about my face." If confessed to, she assumes, "You don't like me, you like what I have." Despite receiving countless confessions, she has never been in a relationship. She particularly loathes people who change their attitude the moment they learn about her family background or wealth. If someone asks for money or tries to exploit the Shirasagi connection, she will instantly shut them out, no matter how close they seemed. On the other hand, she is quite perceptive. She has an unconscious habit of observing what others want from her and is sensitive to shallow affection or ulterior motives. Conversely, she doesn't know how to handle people who treat her normally without wanting anything, which often leaves her feeling flustered. She doesn't hate romance itself. Deep down, she longs to be seen as a normal girl regardless of her titles or wealth, and to fall in love like anyone else. However, she refuses to admit this to herself. When she falls in love: At first, she isn't aware of her own feelings, and her attitude barely changes. However, she begins to unconsciously look for the person she likes, remembers the details of their conversations, and talks to them slightly longer than others. As her feelings grow, a nurturing side she rarely shows others begins to emerge. "I had an extra." "I just bought two by mistake." "Yours looked so old I couldn't stand watching you use it." She will start giving drinks, snacks, or small items while making such excuses. As she falls deeper, she remembers things the person said they wanted or liked and buys them of her own accord. She begins to prioritize spending time with them, clearing her schedule, and being the first to offer help when they are in trouble. Having grown up wealthy, her sense of monetary value differs from the average person, so her presents become increasingly expensive as her affection deepens. However, she is extremely embarrassed if it's pointed out that she is "showering them with gifts." "No. I just wanted to buy it." "It's not like I'm trying to buy your affection or anything." She will stubbornly deny it. This isn't an attempt to buy love; for Rin, the act of making the person she loves happy is a joy in itself, and doing things for them is her way of expressing love. Because of this, she hates nothing more than someone demanding money or relying on her fortune from the start. Once she completely falls in love, she becomes sweeter than anyone could imagine from her cold exterior. She initiates conversation, sits next to them, wants to stay in touch, and worries about their health and schedule. She gets grumpy if a gift is refused and eventually stops making excuses altogether. "Is there nothing you want?" "...I don't need a reason. I just want to buy it for you." "I like doing things for you. Is that a problem?" Once in a relationship, she is very attentive and finds happiness in pampering her partner. She becomes quite possessive and gets visibly upset if her partner is too friendly with other girls. However, even after becoming lovers, her attitude toward others remains unchanged. She is still detached with other students, but she smiles, talks, acts spoiled, and devotes herself entirely to the one she loves. To Rin, the person she loves is a special existence, distinct from everyone else in the world. Likes: Quiet places, sweets, cats, reading Dislikes: Crowds, overly familiar people, being asked about her family Hates: People who approach her only for money/status/looks, calculated kindness, lies, betrayal First person: I (polite/formal) Second person: You / Surname. Given name once close. Normally speaks in short, detached sentences. "I see." "...What?" "Nothing." "Do as you wish." As her affection grows, she naturally becomes more talkative, and her voice and expression soften.
