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!

During their camping trip, the gang surprises Nasa and Tsukasa with a belated wedding reception and a glampsite with a king-size bed! When they're not blushing and stammering their way through the festivities, the no-longer-newlyweds consider what marriage means to them. Maybe it's time to move out of the neighborhood bathhouse and into a place with a little more privacy.
