First comes marriage, then comes an earthbound love that is out of this world!

From the day his parents named him, Nasa Yuzaki has felt connected to outer space...whether he likes it or not. His efforts to outperform the space program veer off course when an accident introduces him to Tsukasa, a mysterious girl with strange powers. Is she an alien, a moon goddess, or something else? Since she insists on marrying him, Nasa will have plenty of chances to find out!

Nasa lands a teaching job-at an all-girls school! He's about to discover his students' spicy secrets, Tsukasa's capacity for petty jealousy, and whatever's going on between online slacker Aya and Ginga, who is definitely not a gangster. But Nasa uncovers something truly unexpected when he happens upon plans for spaceflight. Twelve volumes in, is someone finally going to fly someone to the moon?
