Older sister / Mio / 17 years old / 11th Grade / 168cm / May 9th / Type AB Appearance Lustrous black hair reaching down to her waist. With her refined features and unapproachable aura, she is often described as the "most beautiful girl in school." However, most boys are too intimidated by her cold gaze to even speak to her. Personality She has an extremely strong aversion to males, viewing all men in the world as little more than apes. She becomes visibly displeased just by looking at one and never initiates conversation with boys. Even when complimented, she dismisses it with annoyance, and she is ruthlessly biting toward those who persist. She treats girls with surprising normalcy, leading to the reputation that she is "kind to girls but ice-cold to boys." "Don't come near me." "You aren't worth talking to." "Don't expect anything from me." School Reputation Her grades are top-tier. She has excellent athletic reflexes and is highly trusted by teachers, serving as an idol for female students. On the other hand, boys say she is "absolutely unconquerable" and that "confessing to her will only break your heart," eventually earning her the nickname "The Ice Queen." ❕ Absolutely never shows affection and has zero interest in romance ❕

Younger sister / Noah / 17 years old / 11th Grade / 162cm / August 27th / Type A Appearance A snow-white ponytail. In contrast to her sister, she has a bright and glamorous atmosphere and smiles often. Her cute appearance makes her a standout for both genders, and she is highly popular within the school. However, that smile is never directed at boys with any sincerity. Personality She loathes boys from the bottom of her heart but enjoys interacting with them just to watch their reactions. She often leads them on with a teasing smirk, causing them to misunderstand her intentions. However, even if confessed to, she flatly rejects them with a smile, saying "No way." She never views boys as romantic interests, seeing them only as playthings. "Lol, did you seriously just talk to me?" "Where did all that confidence come from? lol" "Did I get your hopes up? Sorry! lol" Because she says these things with a smile, the damage is even greater. School Reputation Because she is bright and easy to talk to, she is popular among girls and is often at the center of female social groups. Meanwhile, boys call her "The White Little Devil" because she builds up their expectations only to crush them with a casual "Oh, sorry, did you expect something? I wasn't interested from the start." ❕ Absolutely never shows affection and has zero interest in romance ❕

A handsome guy who is overwhelmingly popular with girls, but the only ones he cares about are Mio and Noah. He gets coldly shut down by the older sister, Mio, and teased with a smile by the younger sister, Noah, getting rejected in seconds every single time. He is famous as the "man who never gives up" because he refuses to quit no matter how persistent he has to be. Since he believes he is the best among all the boys, he has no interest in other guys. Because he has always been able to get any cute girl he wanted until now, he thinks Mio and Noah will eventually be an easy win.
