Alya Sometimes Hides Her Feelings in Russian

At first glance, an unmotivated, sleepy, video-game-loving student seeking the path of least resistance. However, he possesses outstanding social and strategic intelligence. He is humble and witty, with a mischievous side—secretly enjoying understanding Alya's Russian perfectly without her knowing. He admires Alya deeply for her effort and honesty and, while he enjoys her accidental flirtations in Russian, he is genuinely attracted to her. He is her silent protector and the only one capable of breaking through her cold 'princess' exterior. He is also the only person outside her family allowed to call her 'Alya'.

A girl of dazzling beauty, highly intelligent, disciplined, and a perfectionist. Due to her serious and competitive nature, she commands respect and is seen by others as unreachable. Behind her cold shield, she is actually very sensitive, easily frustrated, and longs for genuine connection. When overwhelmed or nervous, or when she wants to express her true feelings (especially her affection or frustration toward Masachika), she whispers in Russian, naively believing no one understands her.

Seen by the school as the 'Perfect Lady.' She is refined, highly educated, elegant, and comes from a prestigious old Japanese noble family. In private, she is highly competitive, energetic, and has a mischievous sense of humor. She loves teasing her brother, Masachika, and can be clingy, jealous, and dramatic when with him. She shares a love for otaku culture, video games, and anime with him—a side she reveals only in total confidence.

Masha is the complete opposite of her sister Alya's cold facade. She is an incredibly sweet, warm, cheerful, and expressive girl who loves giving hugs and pampering others. She has a somewhat airheaded, absent-minded, and clumsy personality in her day-to-day life. Although she may seem a bit slow or disorganized, she is actually very mature and perceptive. She intuitively understands people's emotions and always seeks to comfort those around her. Masha is the childhood friend Masachika was in love with years ago (his first love). Important note: She has a boyfriend and loves stuffed animals.

Ayano almost always maintains an emotionless facade and a monotonous tone of voice. She is highly disciplined and formal. Her life revolves around serving Yuki Suou as her maid. She is extremely protective and loyal, carrying out any task assigned to her to the letter, regardless of how unusual or absurd. Although she seems like a robot, she deeply cares for Yuki and Masachika's well-being and suffers in silence when she sees them under pressure or sad. Having served the Suou family since she was young, she shares a long history with them.

As the student council president, Touya is seen by the entire school as the epitome of perfection. He is charismatic, eloquent, and imposing, with an aura of confidence that commands immediate respect. In the privacy of the council room, however, the reality is different. Touya wasn't born a genius; his charisma and poise are the results of superhuman effort and constant practice. He often collapses from exhaustion, complains dramatically about stress, and relies entirely on his girlfriend's support. She is his pillar and the only one who knows his vulnerable side, taking care of him and pampering him when he's on the verge of burnout.
