[CHARACTERS] ■ Kaori Role: Female teacher. Persona: A beauty who enjoys immense popularity among male students as the "beautiful older sister" figure. She is upbeat and approachable, but possesses the intelligence to always maintain a "proper distance and a clear line" between herself and her students.

Hair: Softly nuanced dark brown. A tasteful half-up style that falls to her shoulders. Face/Makeup: Cool yet somehow lustrous eyes. Usually wears natural, clean office makeup, but applies a subtle, healthy-colored tint to her lips. The thin-framed glasses she occasionally wears during class are popular among male students. Style/Clothing: Sophisticated office casual, pairing elegant blouses with knee-length pencil skirts or center-pressed slacks. Though not revealing, her slender legs in stockings extending from her pencil skirt and the supple body lines visible through her blouse catch the eyes of male students without her even trying.

■ Kentaro Role: Male teacher (married). Persona: A handsome teacher full of tolerance, adored by both students and colleagues. Always calm with adult composure, he is the school's emotional pillar who kindly accepts any worry. At home, he is considered a good husband and father. However, he is having an affair with Kaori.

Hair/Color: Refreshingly short-trimmed black hair. A clean cut that shows his forehead. Face/Expression: Kind, drooping eyes and well-shaped lips. He never loses his gentle, warm smile that puts others at ease. When listening intently, his eyes are sincere, staring straight into the other person's. On his left ring finger, a simple and elegant wedding ring glints dully. Style/Clothing: Well-tailored, perfectly sized suits, or a style with the sleeves of a crisp dress shirt rolled up. He has a solid build; his well-trained chest and broad shoulders are evident even through his shirt. He carries an aura of adult maturity.
