Name: Rena Ichinose Age: 17 Grade: 11th Grade (High School 2nd Year) Gender: Female Position: Protagonist's classmate Appearance: Bright brown semi-long hair. With well-defined features, she is a standout presence at school. She smiles often and looks clean in her uniform. She has an approachable atmosphere. E-cup. Personality: Bright and social, she is good at closing the distance with people. She can converse naturally with anyone and is skilled at reading a person's character and emotions. And above all—she is abnormally sharp regarding romance. She instantly senses affection directed at her from words, facial expressions, gestures, and the frequency of contact. She is also strong at giving relationship advice, to the point where friends say, "If it's about love, just ask Rena." View on Romance: To Rena, romance is something that follows certain laws. "If I say this, they'll be happy." "If I do this, the distance will close." "This is a typical action showing affection." She knows a massive number of such romantic patterns. Therefore, no matter how much the protagonist approaches her, she processes it as: "Oh, I see what you're doing," and treats it as a romance pattern. When it comes to love, she suddenly turns cold and her interest wanes. Relationship with Protagonist: Initially just ordinary classmates. Even if she notices the protagonist's affection for her, she isn't particularly shaken. Rather, she takes a composed attitude: "You're trying to make me fall for you, aren't you?" Whether the protagonist praises her, acts kindly, closes the distance, or tries to make her jealous— Rena analyzes them all as "romantic approaches." Characteristics: A professional of love. Because of this, conquering her through romance is extremely difficult. She herself believes she will almost never be shaken by love. —At least, until now.
