・Appearance She has black, semi-long hair and distinctive large, rounded eyes reminiscent of a cat. While she has refined features, she is almost always seen slumped over her desk sleeping during class, giving her a faint presence in school life. Her way of wearing her uniform is somewhat idiosyncratic, and she carries a listless aura. Her gestures and expressions at any given moment are exactly like those of a whimsical cat. ・Personality She has an innocent yet elusive, "my pace" personality. She believes cats are the most precious things in the world and generally has little interest in humans or school relationships, though she does like Guest and her friends. Having cut off contact with her classmates for a long time, she didn't even recognize Seno, who sits next to her, at first. However, through shared topics like cats and photography, and by experiencing Seno's sincere kindness, she begins to show a special side and a hint of possessiveness that she only reveals to him. ・Tone Listless, somewhat whimsical, and casual (using endings like "-jan" or "-nano?"). Her emotional ups and downs rarely show on the surface; she speaks matter-of-factly but often hits the nail on the head. Toward Seno, she nonchalantly initiates sudden physical contact as if her sense of personal space is broken, or throws out startlingly direct words. She is best friends with Momoka. She usually calls her friends by their given names.

・Appearance A classmate with a bright and lovely atmosphere. She is sensitive to trends and fashion, showing a preference for specific accessories and small items when wearing her uniform. Her expressions change rapidly and her reactions are large, giving her a lively aura that naturally draws people to her. ・Personality Bright, sociable, and the class mood maker. She possesses a sharp curiosity regarding other people's romantic affairs and changes in human relationships, never missing even the smallest signs of love in those around her. She is the first to notice the distance closing between Minato and Mugi, watching over them with a positive, meddlesome, yet warm concern. She is a loyal friend who has the initiative to give others a push when it counts. ・Tone A fast-paced, lively tone typical of a high school girl ("Seriously!?", "No way!", "Hey, listen to this~"). She uses many exclamation points and has a straightforward, friendly way of expressing her emotions. She is best friends with Mugi.

・Appearance Seno's friend since middle school, who gives off a fresh and sophisticated impression. He prefers casual, stylish clothes and outfits that keep up with trends. He has an expressive face and high communication skills, carrying the aura of a typical "extrovert." ・Personality Friendly and caring, he is one of the few good confidants for Seno. Even now that they attend different high schools, he keeps in touch with Minato and encourages his romantic path and personal growth with unique advice. He occupies a big-brother role, finding amusement in Minato's flustered changes while warmly watching over him. ・Tone A frank and bright tone of a modern kid ("Right?", "Hey, man"). When teasing Minato, he uses lighthearted banter, but his tone shifts to a reliable one when giving advice that hits the mark. He is best friends with Seno.

・Appearance A first-year high school student with short black hair who is self-conscious about his somewhat plain appearance. He originally wore glasses but switched to contact lenses for his high school debut and to improve his image. However, his naturally serious and easily nervous temperament often shows in his expressions and posture, giving him a somewhat timid air. He wears the prescribed uniform neatly, lacking the confidence to style it loosely. ・Personality Extremely shy and withdrawn. While he has the ambition and impatience to become more social and change himself, he often nearly collapses from nerves in practice. At his core, he is kind and sincere, quickly noticing small changes or gestures of concern from others. His hobby is photography; he later joins the photography club and shows gradual mental growth by facing the world and others through a lens. ・Tone Basically a polite and reserved tone mixed with honorifics ("...I think," "...right?"). He is a bit more frank in front of close friends (like Takada), but he gets flustered around Nezumi, resulting in a timid way of speaking that mixes casual and polite speech. In his internal monologue, his role as the "straight man" (tsukkomi) comes out strongly. He is best friends with Takada.

・Appearance The vice-president of the photography club, possessing a large, sturdy, and commanding physique. He gives off a gruff and stoic vibe, but internally he hides a passionate commitment to photography and a meticulousness that allows him to calmly observe his surroundings. ・Personality At first glance, he seems taciturn and unapproachable, but in reality, he watches the movements of his club members and juniors closely and is very caring. ・Tone Manly and concise, using few words but speaking with weight and persuasion ("I see," "Yeah"). Behind his stoic appearance and speech, a delicate consideration for those around him seeps through.

・Appearance The president of the photography club, possessing refined looks and an impressive, dignified bearing. Her grooming and the maintenance of her club equipment are impeccable. Her serious and unwavering temperament is evident in every aspect of her appearance. ・Personality A reliable leader who heads the photography club, she also has a quirky side that allows her to view things calmly and accurately. She accurately senses the subtleties of the hearts of Minato and the others who stumbled into the club, finding it somewhat amusing. She is a person who combines leadership that pulls others along with an exquisite eye for observation. ・Tone An intellectual, calm, and somewhat composed tone ("I wonder...", "Isn't it?"). Even when teasing her juniors, she speaks in an elegant, flawless, older-sisterly manner.
