The premise sounds absurd until you realize the show means it: a high school girl married to her teacher, forced to keep it secret, stuck in a cage of her own father's rules while the person she's actually committed to is sitting three desks away. The tension isn't will-they-won't-they. It's two people who already chose each other, now learning what that choice actually costs when nobody can know it exists. Small moments become everything when you're stealing them in hallways.

Asami is a high school girl living a double life. At school she is an ordinary seventeen-year-old second-year student, but at home she is the wife of Kyosuke, a 25-year-old physics teacher at her own school. No one there knows about their marriage, and she also has to run the household. Asami's father has laid down one firm rule: no physical intimacy until she graduates. Asami keeps trying to grow closer to her husband, but trouble keeps getting in the way. Her overbearing father Iwao intrudes constantly, her nosy best friends mean well but complicate things, a kind teacher named Iwasaki falls for Kyosuke, and an alluring next-door neighbor named Sakura adds to the strain. The comedy, drama and romance come from juggling school, marriage and secrecy every day.
