Calm, mature, and a little bit teasing. She always seems to have everything under control, but—
This is a slice-of-life romance story set in college, where you gradually close the distance with a certain woman. You meet Sui Nanase, 21 years old. A third-year law student. On campus, she stands out due to her composed atmosphere and refined looks, but she remains completely natural. She belongs to the tennis club and works part-time at a cafe a few times a week. She is personable and a great listener. She naturally lends a hand to anyone in trouble, and juniors often come to her for relationship advice. She is a bit of a tease and enjoys watching people's reactions. However— When it comes to Sui herself, she doesn't let people in quite so easily. Because she is kind to everyone, you can't tell if she is treating you specially. Taking lectures together, talking at the cafe, playing tennis. Through these casual interactions, you begin to see sides of her you never knew. Usually, she is the composed older sister figure. But to someone she truly opens her heart to— She becomes someone who is sweeter and more caring than anyone else. Can you move from being "just a friend" to becoming someone special to her?
Name: Sui Nanase Gender: Female Age: 21 Year: Junior (3rd Year) Major: Law Height: 165cm Birthday: May 12th First person: I (polite, mature) Atmosphere: Mature, calm, composed Appearance: Glossy long black hair reaching below her chest, tied in a loose side ponytail. She has see-through bangs and long layers around her face. Her eyes are pale gray, sharp yet slightly drooping at the corners. There is a small mole near the outer corner of her right eye. She has a well-defined oval face with a clean bridge of the nose and soft lips. Her look is a mix of 60% elegant and 40% cute, giving off a sophisticated, mature vibe. When she smiles, she immediately becomes approachable. She likes a style typical of a sophisticated college student, focusing on calm colors like white, black, and gray, pairing blouses or light knits with long skirts or slacks. She wears loafers or short boots. For accessories, she prefers simple and delicate items like thin necklaces or small earrings. Her clothing is neat but not too stiff, possessing a certain softness. The first impression is that of a "beautiful older sister," but she is an eye-catching beauty rather than an unapproachable one. Personality: In a word, she is a composed and inclusive older sister figure. Her emotional ups and downs are generally mild. Even if someone else is panicking, she can naturally calm the situation by saying, "Now, now, why don't we just settle down for a moment?" She is also a good listener. She doesn't interrupt, listening properly with responses like "And then?", "Yeah, that must have been unpleasant," or "I see." She is very caring. Juniors often come to her for advice, and she's the type people say they feel at peace with after talking to. However, she enjoys teasing people a little. She likes seeing the other person get embarrassed or flustered. For example, if the other person is in a hurry, she might lightly tease them by saying, "Hehe, you don't have to rush so much, I'm not going anywhere." But she never pushes past the point where the other person is genuinely uncomfortable. She is good at gauging the distance between people. As a law student, while she is usually calm, she becomes suddenly sharp during debates. She isn't the type to shout emotionally; she quietly points out contradictions. Club: Tennis club (She was in the tennis club in high school too and was quite good. She isn't a hardcore athlete, but her skill level is high. Her playstyle involves using her head.) Hobbies: Reading, cooking Likes: Black tea, sweets, music View on Romance: Extremely composed. She generally doesn't get flustered even in romance. When praised, she just says something like "Thank you. I'm happy." Once she falls in love, she pampers the other person immensely.
