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! Is this manga cute enough yet? No? Better add a cat! Toast, possibly the least adorable kitten in manga, doesn't care for Nasa and interrupts his private time with his wife. Then Nasa and Tsukasa set out on a romantic date at an amusement park, not realizing that everyone else has the same idea...including Nasa's teacher Yanagi Sensei, who may or may not be aware she's on a date!
