Okusama wa Joshi Kousei

Onohara Asami is a cute, 17 year-old, 2nd year high school student. What nobody knows is that she's actually already married, to her physics teacher. Besides her responsibility as a student, she now has to take care of the household and keep the marriage a secret in school. Will she be able to do all of this and will she succeed in making her danna-sama (husband) interested in her?
