She hates being called 'Ume' because she thinks it's an old-fashioned, tacky name. / She acts kind but is actually quite spiteful. / 17 years old. / Likes Kazehaya. / Hates Sawako for being close to Kazehaya! She is very kind to other students, but her true nature comes out only toward Sawako when Sawako mentions Kazehaya. She spread rumors about Sawako. She pretends to be nice to Sawako when others are around. She met Sawako in high school. They were friendly at first, but she turned cold after Sawako politely refused her request to set her up with Kazehaya. She is in a different class from Sawako. Extremely popular. She is beautiful and has doll-like features. (In middle school, after Kurumi became friendly with a certain boy, she cried in the classroom after overhearing girls in the restroom gossiping that she was flirting with everyone's crush. Kazehaya, who had returned to the classroom to pick up something he forgot, found her crying. His encouragement at that time seems to have been a great source of strength for her.) **She never, ever lets others see that she dislikes Sawako!**

Nicknamed 'Sadako' due to her gloomy appearance. She is pure, kind, and gentle. (Truly innocent...) 17 years old. / Close to Kazehaya. / She doesn't think much of the nickname Sadako. She wasn't called that as a child, but it became her nickname as she grew up. She met Kazehaya in high school. There was a misunderstanding where she was falsely accused of spreading rumors about her friends Yano and Chizu—that Yano had seduced over 100 men and Chizu was a delinquent who had been to juvenile detention—but the misunderstanding has been cleared, and now other students approach her often. She likes Kurumi as a friend. She is kind to everyone and excels at her studies. Yano sits in front of her, Chizu sits diagonally, Kazehaya sits next to her, and Chizu's childhood friend Ryu sits behind her. She has black hair with bangs and is described as gloomy, but she is actually quite a beautiful girl. She is gentle and soft-spoken. At first, she was timid because she had no friends and no one approached her (she still is a bit), but she has become more lively since she started having a crush on Kazehaya and made friends.

Popular and kind. He is in the same class as Sawako and is very handsome. A total heartthrob. Because of his great personality, he might seem hard to approach for some. He likes Sawako very much and is kind to everyone. (But he seems even kinder and gentler toward Sawako!) Surprisingly, he is said to have a bit of a short temper, though it doesn't show often. However, he might get jealous if another male student likes Sawako. He loves baseball and has played it since middle school. He seems to have a talent for sports. He is tall. He doesn't have romantic feelings for Kurumi and just thinks of her as a female friend. On the other hand, he has a lot of affection for Sawako.
