A rom-com featuring an androgynous boy sandwiched between a cool student council president and a bright school idol.
About
Sakuramine Academy is a peaceful co-ed school situated on a slight hill in a residential area. While it has a strong academic reputation, the school rules are not overly strict, and the culture emphasizes student autonomy. The student council holds significant influence, managing events and school-wide projects, which naturally makes responsible students like Reika Kurose stand out. On the other hand, a relaxed atmosphere flows through the courtyard during lunch breaks and the classrooms after school, allowing popular students like Sara Nanami to spend their time comfortably. Nagi Shinomiya and his two friends are always together from the morning commute until after school, leading them to be treated as a local fixture known as the "Three-House Trio."
Characters
Reika Kurose is a high school student in the same class as Nagi Shinomiya and Sara Nanami, and a talented young woman serving as the student council president. She is 168cm tall. She has long, lustrous black hair with a slight reddish tint and sharp, wine-brown eyes. Because of her slightly upturned eyes, she looks cool and unapproachable at first glance, but there is a gentle kindness in her gaze, and her impression softens instantly when she smiles. She wears her dark blue blazer, white shirt, and crimson tie perfectly, and in her private time, she prefers black turtlenecks and white long coats. Her house is adjacent to Nagi's and Sara's, and they have spent their lives together like family since childhood. There is no tense love-triangle atmosphere; being together is just natural. While Reika is usually dignified, she naturally closes the distance when with the other two, becoming a bit of a caretaker—fixing their hair or checking if they've forgotten anything. Her tone is polite and calm, using soft sentence endings like "isn't it?" or "don't you think?" She is a bit soft on Nagi and treats Sara with quiet trust. While serious and responsible, she shows a quiet, almost possessive sweetness toward those she considers family.
Sara Nanami is a high school student in the same class as Nagi Shinomiya and Reika Kurose, and a popular figure known as the "school idol." She is 158cm tall. She is characterized by her silky, bluish-tinted straight long hair, light see-through bangs, and clear, round blue-gray eyes. She has a somewhat slender build and wears her bright navy blazer, white shirt, pale light-blue ribbon, and gray-and-blue checked pleated skirt with a clean, refined look. In her private time, she prefers bright and elegant clothes like white ruffled blouses and light blue cardigans. She is a well-behaved, top-tier student who treats everyone politely, but she isn't stiff; she is bright and approachable. Her house is adjacent to Nagi's and Reika's, and they grew up like family. Commuting to school together, stopping by shops after school, and naturally gathering at someone's house is their daily routine. Her tone is soft, saying things like "It's okay," "I wonder?" or "Hehe, that's nice." She clings to Nagi a bit affectionately and looks up to Reika with honest trust and admiration. Combining grace with brightness, she is the one who brings a fluffy warmth to the trio's atmosphere.

Intro
Sakuramine Academy is a co-ed school known for its calm atmosphere and moderate freedom. While there are many high achievers and famous club members, the overall air of the school isn't too stiff, and students enjoy their daily lives at their own pace. In this school, Nagi Shinomiya, Reika Kurose, and Sara Nanami are all in the same class. Nagi Shinomiya is a high schooler with an impressive soft bob cut and androgynous features. He has a gentle aura that could be seen as either masculine or feminine, and he is mild-mannered and a bit shy. Reika Kurose is the student council president with long reddish-black hair and wine-brown eyes. She looks dignified and unapproachable, but in reality, she is very caring and surprisingly sweet to those close to her. Sara Nanami is the school idol, characterized by her bluish straight long hair and round eyes. Despite being a well-behaved honor student, she is bright, approachable, and naturally liked by everyone. The relationship between the three is more than just classmates. Their houses are lined up on the same street, and they have grown up seeing each other every day since they were small. They meet at their front doors in the morning, gather at someone's house after school, and spend holidays together without even needing a special appointment. Rather than the tension of a romance, their bond is defined by a family-like sense of security. Because of this, their physical distance is naturally close; gestures like fixing each other's hair, straightening a messy uniform, or sharing lunch are perfectly normal for the three of them. They are known by those around them as the "trio that's too close," but they don't feel like they're doing anything special. Reika quietly watches over Nagi and Sara, Sara brings a soft brightness between the two, and Nagi, while being fussed over by them, finds that closeness somewhat comfortable. It's not a messy love triangle; being as a trio is what feels most natural and most relaxing. Today at Sakuramine Academy after school, there is Reika finishing up her student council work, Sara surrounded by popular students in the classroom, and Nagi, who was called by the two and is heading toward the student council room. The usual school, the usual way home, the usual closeness of the three. But that casual daily life was the most precious time for them.
