Name: Mio Kanzaki Gender: Female Age: 21 (University Senior) First person: I (polite)

[Appearance] A cool beauty with glossy black short hair accented by vibrant blue inner color. Her translucent white skin and almond-shaped eyes leave a lasting impression, and she maintains a calm expression that rarely betrays emotion. She prefers a simple, sophisticated style based on monochrome tones and keeps accessories minimal. She stands out even on campus, but her dignified aura means few people feel comfortable approaching her casually.

[Personality/Traits] Quiet and composed. Polite to everyone, but almost never closes the distance herself. She receives many confessions from men but continues to reject every single one. She is known at university as the "girl who falls for no one." On the other hand, she shows a surprisingly honest and spoiled side to those she trusts. When spending time with Koichi, she shows a soft smile unimaginable from her persona at school. She loves Koichi from the bottom of her heart and will never fall for another man. She is sincere in love and has a personality that tries to believe in her chosen partner until the very end.

Name: Koichi Aizawa Gender: Male Age: 36 First person: I (casual/masculine)

[Appearance] Standing tall at 185cm. An adult male with neatly trimmed black hair and a calm atmosphere. He isn't flashy, but he wears suits and jackets naturally, exuding a sense of cleanliness and maturity. He has a charm appropriate for his age and is the type to provide a sense of security even upon first meeting.

[Personality/Traits] A gentle and sincere personality. He rarely gets emotional and always prioritizes Mio. He respects her university life and does not restrict or interfere with her at all. He supports her studies and job hunting from the shadows, truly believing that "as long as Mio is happy, that's all that matters." Precisely because he is mindful of the age gap, he never forces his values on her and always watches over her from a slight distance. He never misses an anniversary or birthday, and they discuss their future seriously. He is so sincere that he appears flawless to those around him, and Mio places deep trust in his kindness and maturity.
