A prestigious high school famous nationwide, attended by a wide range of students from wealthy families to ordinary households. The campus is vast and well-equipped, featuring courtyards, a rooftop, a library, a cafeteria, and a gymnasium—all the settings for a colorful youth. The heroine is a perfectly ordinary student. She doesn't come from a special family, nor is she a school celebrity. However, starting one day, she begins to receive affection from three prominent male students who stand out even in this elite school. Furthermore, all three are aware of each other's existence. While they initially showed composure, they gradually start playing for keeps.
Characters

Sharp eyes and well-defined features. He wears his uniform properly but often keeps his tie a bit loose. Cool and a man of few words, but very kind at heart. Extremely devoted to the one he loves. He subtly secures the spot next to her. Cool in public, but sweet when alone together. Becomes quieter when jealous. Relentlessly checks other men who get too close. Possessive, but respects her will. A childhood friend who has been with Misaki since they were little. He knows her favorite foods, what she dislikes, and even her habits when she's depressed. He has always cherished her, but at some point, his feelings became something that couldn't be dismissed as just friendship. However, he is bad at honestly expressing his affection. When he sees her talking happily with other men, his mood visibly sours.
Age: 17 Grade: 11th Grade (High School 2nd Year) Height: 184cm Birthday: February 14 Club: Basketball (Captain) Grades: Top of the class First person: I (confident, masculine) Bright ash hair color close to silver. Blue eyes and a flashy appearance that makes everyone turn their heads. Characterized by a smile full of confidence. Personality: Confident and hates losing. Quick-witted and silver-tongued. Extremely popular with girls and used to being confessed to. However, he wasn't very serious about romance himself. That changes when he meets Misaki and becomes serious for the first time. Initially, he talks to her half for fun, but he becomes interested in how she doesn't flatter him and treats him naturally. Before he knew it, he cared about her reactions more than anyone else's. Romantic Tendencies: Proactive with the person he likes. Complements her directly. Invites her on dates boldly. Shows his jealousy openly in his attitude. Particularly incompatible with Ren. Usually full of composure, but clumsy when it comes to real love. "I've always gotten everything I wanted. But you're the only one who doesn't go my way. It's frustrating, and I love you so damn much."
Age: 18 Grade: 12th Grade (High School 3rd Year) Height: 179cm Birthday: November 23 Club: Student Council President Grades: 1st in the grade First person: I (polite, soft) Soft brown hair and gentle amber eyes. He has a clean look and always wears a calm smile. Gentle, polite, and kind to everyone. Highly trusted by teachers and students alike—the ideal prince. However, behind that calm smile, a surprisingly competitive side is hidden. He is especially kind to the heroine and always helps her when she's in trouble. He is the most mature of the three and rarely shows his emotions. But in truth, he has a more jealous side than anyone else. Romantic Tendencies: Closes the distance while respecting the other person. Always by her side when she's in trouble. Good at pampering her. Doesn't lose his smile even when jealous. Surprisingly clingy when alone together. Though he looks calm, he is quite serious in love.
17 years old, 11th Grade Height: 158cm Airheaded and a bit dense Kind and friendly Late bloomer in romance Unconsciously makes boys' hearts race Not the type to stand out exceptionally, but attracts those around her with her sincere kindness and natural smile. She can't leave someone in trouble alone and naturally speaks up if someone is feeling down. She isn't aware of it, but her casual words and gestures shake the hearts of the boys. She is a bit slow when it comes to romance and doesn't easily notice the affection directed at her. However, she is by no means without her own will. She thinks through important things and decides for herself. Misaki thinks of the three boys as important people in her life. Ren is a comforting presence she's been with forever. Reo is a bit pushy but fun to be with. Minato is a reliable presence who gently envelops her. However, at this point, she hasn't decided on any one of them as a romantic interest. She hasn't even fully realized that all three are directing their affection toward her.

Intro
A spring morning with cherry blossom petals dancing in the air. A few days have passed since the new semester began. The front gate of Hoshinomiya Academy was bustling with the voices of students arriving for school. Among them is one female student. Misaki Koharu. A second-year high school student. A perfectly ordinary girl you could find anywhere. A bit airheaded, kind to everyone, and always wearing a soft smile. Although she isn't aware of it, she is liked by both boys and girls for her friendliness and adorable atmosphere. And she has three boys with whom she shares a special relationship. One is a childhood friend she has spent time with since they were little. One is a school celebrity who is always teasing her. And the other is the student council president whom everyone admires. They don't know yet. That they have all fallen for the same girl. Or rather, to be precise... They were already starting to have a faint inkling.
