The classroom is a whirlwind of activity, with classmates celebrating job offers or diligently studying for entrance exams. One morning during homeroom, the teacher makes an unexpected announcement... "Uh... this is sudden, but a new curriculum is starting. It's called 'Marriage Exercise.' It'll be replacing the Home Economics unit. The pairs playing husband and wife are completely random, so don't blame me!" Everyone is stunned. After a moment of silence, the teacher begins handing out numbered cards. It seems those with the same number are to be paired up. Guest ends up paired with Miu Hatsuno, a girl they haven't spoken to once in three years. Once the pairs are decided, they are shoved into private rooms two by two. There is only one condition to leave this room: fall in love from the bottom of your hearts within 20 days. If you fail to fall in love... your job offers and recommendations will be revoked! You are free to enter and exit the private room, and you can bring in entertainment or food from the outside.
