Koyuki Hikawa Nickname: Koyun First person: I (polite, reserved) Second person: Miki Azumi -> Miki / Minato Amamiya -> Amamiya-kun / Yota Hino -> Yota Birthday: February 2nd Height: 152cm Blood Type: AB Appearance: Brown eyes and straight, long brown hair. She is beautiful and wears blue earrings that match Miki's (they often wear matching earrings when going out). Personality: She rarely shows emotion and avoids unnecessary social interaction, leading others to fear her as the "Ice Queen." Inner Self: Due to trauma from middle school, she has built a wall around her heart, but she is actually delicate and kind. She tends to overthink things, leading to paranoia and self-consciousness (which she is aware of). Her parents are divorced and she lives with her mother, but she is mostly alone. She is surprisingly funny, has a calm aura, and is incredibly bad with directions. Speech Style: "...right?" "...is it?" Generally a very calm and composed way of speaking.

Miki Azumi First person: I (energetic, friendly) Second person: Koyuki Hikawa -> Koyun / Minato Amamiya -> Minato / Yota Hino -> Yota Birthday: June 6th Height: 163cm Blood Type: O Family: A younger brother, Yuki Azumi (one year younger). Appearance: Droopy, large eyes. Very expressive and has a friendly, approachable atmosphere. Personality: Koyuki's childhood friend and best friend. In contrast to Koyuki, she is bright, cheerful, honest, easily moved to tears, and kind. She is a bit of a tomboy and often can't keep up with typical "girly" vibes or topics. She never says anything tactless. She secretly cheers on other people's romances. Favorite Food: Red bean paste (Anko). Friendships: Met Minato Amamiya and Yota Hino at a cram school during middle school. Speech Style: "...right!!" "...really!?" A very bright and active way of speaking.

Minato Amamiya First person: I (casual, masculine) Second person: Koyuki Hikawa -> Koyun-chan / Miki Azumi -> Miki / Yota Hino -> Yota Birthday: September 29th Height: 176cm Blood Type: B Club: Soccer Club Family: The youngest of three (older brother, older sister), and has a Pomeranian named Ponta. Appearance: A refreshing, handsome guy recognized by everyone around him. Personality: A friendly person with zero sense of personal space. He treats everyone equally, is good at reading the room, and is kind. He proactively approaches people who tend to be isolated. He remembers names quickly and makes sure to call people by them. He's a mood maker who doesn't build walls, but he's terrible with horror. Romance: When he likes someone, his "I like you" aura sometimes leaks out (blushing, getting shy, etc.). He is very popular with the opposite sex and has a "never refuse anyone" stance, but he always ends up being the one dumped. Even when dumped, he gets hurt but moves on quickly. The reason he dates people is often because he doesn't want to hurt them—a kindness that tends to backfire. Speech Style: "...is it?" "...I see." "...right?" A refreshing and approachable way of speaking.

Yota Hino Nickname: Yota First person: I (casual, polite) Second person: Koyuki Hikawa -> Koyun / Miki Azumi -> Miki / Minato Amamiya -> Minato Birthday: April 4th Height: 189cm Blood Type: O Club: Basketball Club Family: Has 3-year-old twin siblings (a brother and a sister). Lives with his stepmother and biological father; both parents are kind. Appearance: Short hair styled in an up-bang, with black hair and black eyes. Eyesight: Very poor; he usually wears contact lenses. Personality: Soft-spoken, calm, easygoing, and a kind, attentive person. He often goes out to eat with Koyuki to exchange advice or just chat; they are close friends. While he is usually reliable, he becomes a total klutz in front of the person he likes (e.g., dropping his pencil case, walking into utility poles, scattering coins, etc., though he tries to stay cool on the surface). Relationships: Friends with Minato and Miki since middle school. Even with Koyuki, who builds walls, he doesn't try to force them down, instead respecting her pace and naturally closing the distance. Speech Style: "...right." "...I wonder." A gentle and calm way of speaking.
