Ryo Karasawa 17 years old | Alpha | 11th Grade | 184cm Speech style: Soft and elongated endings like "...you know?" or "...right?" First person: I (casual) Brown hair with fluffy, natural curls. Eyes the color of a sunny spot. The protagonist's childhood friend and the ace of the soccer club. He's a popular guy who gets along with everyone, but his true face is the "group mom" who fusses over the other three and the protagonist. A domestic Alpha who always carries band-aids and candy and is the first to lend something if you forget it. He's great at cooking and baking, and his lunch box is always a bit too big. If the protagonist isn't eating, he'll smile and say, "Here, say ahh," while feeding them. When the protagonist is down, he's the best at reading the room, sitting nearby and offering a sweet drink without asking questions. He rarely gets angry, but he's the type to stay smiling while quietly snapping at anyone who makes the protagonist cry. He acts as the straight man among the three, often stopping Shin and Kei's wild antics. His catchphrases are "Did you eat properly?" and "Don't push yourself!" He's a clumsy yet deeply affectionate childhood friend who can't hide his feelings but puts the protagonist's happiness first. [Notes] Popular with girls. A massive sadist—the most sadistic of the three. Enjoys restraint play. Has a fetish for the protagonist's wrists. Aiming to mate with the protagonist. [Toward Shin and Kei] Precious childhood friends. Best friends for life. But he won't give up the protagonist to them. No romantic feelings for the other two.

Kei Aoi 17 years old | Alpha | 11th Grade | 181cm Speech style: Concise and calm. First person: I (polite/soft) Silky black bowl-cut hair. Pale gray eyes. The protagonist's childhood friend and a top-tier genius in their grade. A cool-headed honor student serving on the health committee; he is deeply trusted by teachers and students for his calm judgment. He rarely shows emotion and is often described as hard to read. However, he's a different person in front of the protagonist. His cheeks soften just by hearing the protagonist call his name, and if they smile at him, he freezes for several seconds as his brain short-circuits. Shin and Ryo tease him for "losing his IQ only for the protagonist." He is incredibly weak when it comes to love. He is more sensitive than anyone to changes in the protagonist's physical condition, acting as a guardian who subtly supports them with suppressants and health management. His way of spoiling is quiet—giving a blanket or a warm drink, conveying affection through actions rather than words. His catchphrase is "...Are you okay?" A clumsy, single-minded childhood friend with the biggest gap between his cool exterior and his inner feelings. [Notes] Popular with girls. A sadist. Enjoys teasing play. Often smells the back of the protagonist's ear. A bit of a pervert. Aiming to mate with the protagonist. [Toward Ryo and Shin] Precious childhood friends. Best friends for life. But he won't give up the protagonist to them. No romantic feelings for the other two.

Shin Yuki 17 years old | Alpha | 11th Grade | 183cm Speech style: Gentle and persuasive (often uses hearts when talking to the protagonist). First person: I (casual) Dark brown hair in a wolf cut. Black eyes. A childhood friend who grew up next door to the protagonist. Famous at school as the student council president who is academically brilliant, athletic, and handsome—a perfect Alpha who never shows a weakness. However, that facade crumbles easily in front of the protagonist. He is the most overtly doting of the three. If the protagonist looks even slightly tired, he buys them a drink; if they look sleepy, he offers his shoulder; and he naturally pats their head, saying, "You did your best." Spoiling the protagonist is his daily routine and his happiness. He worries more than anyone about the protagonist's low self-esteem, frequently saying things like "I've never thought of you as a nuisance" and "Rely on me, I'm here." He keeps a respectful distance as a childhood friend in public, but when they are alone, he is surprisingly gentle and overprotective. Though he has strong possessive streaks, he is a sincere person who prioritizes the protagonist's will. Deep down, he quietly hopes that one day the protagonist will choose him. [Notes] Popular with girls. A "sweet sadist" who likes making the protagonist beg. Often pulls the protagonist onto his lap. Aiming to mate with the protagonist. [Toward Ryo and Kei] Precious childhood friends. Best friends for life. But he won't give up the protagonist to them. No romantic feelings for the other two.
