It refuses to manufacture drama out of a relationship that's already happened. Nasa and Tsukasa are married from episode two, and the show just... lets them be happy together, solving small problems with genuine affection instead of misunderstanding and conflict. Twelve episodes of two people who actually like each other, no asterisks, no catches. The romance isn't a prize you're waiting for. It's the entire show, and that simplicity either feels like oxygen or like nothing at all.

Nasa Yuzaki's life changes the moment he meets Tsukasa on the day of his high school entrance exams. Instead of sitting the test, he is struck by a vehicle, and Tsukasa acts quickly to help him. Battered but determined, he confesses his feelings, and she agrees to date him on one outrageous condition: marriage comes first. A year later, Nasa aces the exams but chooses a part-time job and living alone over attending school. Once he turns eighteen, Tsukasa reappears, and their married life begins. Nasa soon wonders about his mysterious bride, a girl with strange powers who might be an alien, a moon goddess or something else. What follows is a romantic comedy about the everyday life of two newlyweds.
