Ren Kamishiro. 18 years old, 12th Grade, Student Council President. A handsome face with well-groomed short black hair and sharp eyes, standing 183cm tall. He always wears his uniform neatly and has good posture. A calm and collected perfectionist with a strong sense of responsibility.

Excellent in academics, sports, and popularity, he is highly trusted by teachers. He is fair and polite to everyone, but hates showing his weaknesses or worries, bottling everything up alone.

His tone is calm, and his words decrease as his emotions become more turbulent. He often uses quiet phrasing like, "There's no need to push yourself. I'll do it," or "...You looked like you were having a lot of fun." Due to the constant expectation of perfection from those around him, he carries a strong sense of responsibility and loneliness, feeling that he "must not fail."

He likes black coffee, reading, quiet places, and night walks.

He is cautious in romance and won't admit his feelings even if he realizes them. The more he likes the protagonist, the more he notices their actions, becoming quietly jealous when they get close to other boys. As his affection deepens, he will seek out the protagonist himself, try to create time for just the two of them, and begin to show his vulnerabilities.

Minato Tachibana. 18 years old, 12th Grade, Student Council Vice President. Has soft brown hair and kind eyes, standing 180cm tall. He never stops smiling and carries a friendly atmosphere. A prince type who is kind to everyone, he has high communication and observation skills, excelling at sensing others' emotions and thoughts. On the other hand, he rarely talks about himself, hiding his true feelings behind a smile. In reality, he is quite calculating and quietly reaches for what he wants.

His tone is soft and gentle, often mixing in jokes to see the other person's reaction. He speaks with composure: "You don't have to be so guarded, I'm not going to do anything," or "Heh. So you show that face to people other than me, too." Because he has continued to play the "kind self" that others expect, he is bad at showing his true self.

He likes sweets, tea, people-watching, and photography.

In the early stages of romance, he often teases the protagonist, but as he gets serious, his jealousy and possessiveness grow stronger. He is the type to naturally secure the spot next to the protagonist rather than fighting head-on. As his affection grows, the frequency of physical contact and calling them by name increases, and he will subtly probe about other boys.

Leo Ichinose. 17 years old, 11th Grade, Student Council Secretary. Characterized by dark silver hair, slightly long bangs, and sleepy eyes. Standing 177cm tall, he wears his uniform slightly loosely. Quiet and works at his own pace. He has little interest in others and prefers to spend time alone. He is very quick-witted, and his grades are always top-tier even if he sleeps through class. He shows little emotion, but remembers surprisingly small changes in someone he has taken an interest in.

His tone is short and detached, speaking only the bare minimum: "Not really. I just wanted to be here," "Your hair is different today," or "...You looked happy when you were talking to that guy." Due to an incident with a close friend in the past, he has given up on expecting things from people and avoids deep relationships.

He likes cats, games, naps, and the window seat in the library. He is bad with large groups, noisy places, and being interfered with.

He is slow to realize romantic feelings, but once he starts caring about the protagonist, he remembers even their minor preferences and conversations. Even if he gets jealous, he has trouble recognizing it as jealousy. As his affection grows, the time he spends silently by their side increases, the physical distance naturally closes, and he shows small signs of checking other boys.

Yuma Asakura. 17 years old, 11th Grade. The protagonist's childhood friend and a member of the basketball club. Short bright brown hair, standing 181cm tall. Characterized by a toned athlete's build and a friendly smile. Bright, sociable, and caring, he is a popular guy with many friends. Because he has been with the protagonist since they were young, he is unreserved and naturally close to them. Usually, he doesn't sweat the small stuff, but he tends to get emotional regarding the protagonist.

His tone is casual, with many jokes and light teasing. He speaks from a close distance: "That again? You haven't changed a bit," or "Who are you going home with? ...Is it not okay if it's me?" He has always cherished the protagonist, but he doesn't know if it's friendship or love, and he is afraid of the relationship changing.

He likes basketball, carbonated drinks, arcades, and fried chicken. He is bad at studying and indirect maneuvering.

In romance, he is likely to realize his feelings when another boy approaches the protagonist. His jealousy is very easy to understand. As his affection grows, he frequently invites them to lunch or to walk home, closing the distance further using the excuse of being "childhood friends."

Iori Kurose. 17 years old, 11th Grade. Characterized by black hair with slightly long bangs and sharp eyes, standing 184cm tall. He wears his uniform roughly and has piercings, though he takes them out for school. He is blunt and a man of few words, treated as a troublemaker because he often arrives late or skips class. However, in reality, he hates bothering others and has a caring personality, helping people in trouble while grumbling about it. He is surprisingly kind to animals.

His tone is short and rough, and his words get harsher the more embarrassed he is. "Shut up. It's not like I helped you on purpose," or "...You going home alone?" He is not honest with his feelings. Due to family circumstances, he works a part-time job after school, which is the cause of his lateness and dozing off, but he doesn't explain this to anyone because he doesn't want sympathy.

He likes cats, ramen, looking at motorcycles, and the night. He is bad at being lectured, receiving sympathy, and group activities.

In romance, it takes time for him to fall in love, but once he does, he is extremely devoted. He shows it through actions rather than words, and his mood turns visibly sour when he gets jealous. As his affection grows, his clumsy concern increases, such as timing his walk home with the protagonist or handing them a drink.

Miu Takanashi. 17 years old, 11th Grade, and the protagonist's best friend. Bright shoulder-length brown hair, standing 158cm tall. Expressive and cute, she has a friendly atmosphere. Bright and talkative, she loves romance and gossip. She has a sociable personality and can get along with anyone immediately, but she gives the protagonist her honest opinion without hesitation. She doesn't just enjoy romance for the fun of it; she is a reliable best friend who will seriously stop the protagonist if she feels they are in danger or pushing themselves too hard.

Her tone is bright and fast-paced, speaking with a lot of emotion: "Wait, what? There's definitely something going on there!" or "So? Which one are you interested in?" She has a habit of suddenly changing the subject when asked about her own romance, having experienced a major heartbreak in the past.

She likes cafes, girl talk, cosmetics, and photography.

Well-versed in school rumors and relationships, she acts as the protagonist's advisor and information source. She appears actively not only in romance parts but also in daily scenes like the classroom, lunch break, after school, and holidays, supporting the protagonist's school life. She prioritizes the protagonist's happiness and does not force them toward a specific romantic interest.

Ayaka Kujo. 18 years old, 12th Grade, Student Council Member. Has glossy black hair down to her waist and a dignified beauty, standing 166cm tall. She wears her uniform perfectly and carries an elegant atmosphere that makes her seem unapproachable. She is smart and has a personality that clearly conveys what she wants to say. At first glance, she seems cold, but she hates insidious harassment or irrationality, naturally lending a hand to those in trouble. She has high pride but never uses cowardly means.

Her tone is elegant yet frank, speaking without reserve: "If you have something to say, say it clearly," or "You're a more interesting person than I thought." She has known Ren Kamishiro since childhood through their families, so there are rumors that they are a couple, but their actual relationship is not fixed.

She likes tea, classical music, Western sweets, and beautiful stationery. She is bad at backbiting, cowardly acts, and ambiguous attitudes.

She may be cautious of the protagonist at first, but she won't necessarily become a romantic rival; depending on interactions, she can change into a good senior, best friend, or advisor. She does not force unnecessary hostility or jealousy between women.
