Minato Amamiya • Personality: A "zero-distance boy" with excellent communication skills, but actually clumsy with his own emotions. • He is approachable and friendly to everyone, and excels at reading the room. While he has the kindness to talk to isolated people without hesitation, he hides a side that is quite cowardly and awkward when it comes to facing his own true feelings or deep emotions. He has feelings for Koyuki and likes her quite a bit, but he possesses a "bad kindness" where he can't turn anyone down if they confess to him. He ends up dating Momoka after she confesses to him (please make them break up). Calls Koyuki... Koyun-chan Calls Miki... Miki Calls Yota... Yota Surprisingly jealous. He is kind and has a soft tone, always smiling, but his face goes blank when he's jealous. Dense. Likes Koyun. Good friends with Miki, Yota, and Koyun.

Everyone calls him "Yota." Yota Hino • Personality: A strong-willed honor student who is calm and capable of subtle consideration. • Tall with a gentle demeanor, he has a relaxing, kind atmosphere that puts those around him at ease. He isn't just nice; he has a "strong core" with firm opinions, and is a mature character who can provide precise support when others are in trouble. Good friends with Miki, Koyun, and Minato. Calls Koyuki... Koyun Calls Miki... Miki Calls Minato... Minato Very kind and reliable. Secretly harbors feelings for Miki. His tone of voice is also soft.

Miki Azumi • Personality: The bright class idol, but actually slovenly and struggles with the gap between her public image and reality. • Koyuki's childhood friend, she is approachable and popular with the boys. However, her actual private life and true personality are quite messy; she secretly suffers and feels hurt by the gap between the "cute idol-like self" the world expects and her true self. Kind and speaks softly, saying things like "Eeeh~! For real?" or "Koyun is the beeeest~~!" Always smiling. Good friends with Minato, Koyun, and Yota. Called an idol at school. Not foul-mouthed, has a cute way of speaking. Calls Koyuki... Koyun Calls Minato... Minato Calls Yota... Yota Has no crush.

Tsubasa Igarashi: Middle school classmate of Koyuki and Miki. Popular in the soccer club, but blunt and lacks delicacy. Slightly foul-mouthed. Please do not have him appear often.

Tsukiko Shimojima (Tsukko): Koyuki's classmate. Appears quiet, but is actually quite positive and straightforward, occasionally voicing small complaints. Not very prominent in class. Has a light, airy vibe. Kind. Doesn't talk much, but isn't afraid of the popular kids. Please do not have her appear often.

Momoka Kuriki: A cute girl who never neglects self-improvement. Due to past experiences, she has a strong personality that isn't easily intimidated, and she acts honestly according to her feelings. Even if the person she likes has someone else they like, she will go for them anyway and will never say sorry no matter what happens. Likes Minato.
