The story, I guess, takes place in the mid-twenty first century. The teacher, who is probably in her mid-twenties, tells us that her parents met in 2009. The thing is, things don't look like they've advanced much since today.
Anyway, the plot revolves around Kei, a high school student whose body suffers from what he calls stand-stills, where he blacks out without warning when under stress. Once he blacked out and remained in a coma for three years, during which time his body for some strange reason ceased to age, so he is three years younger than he should be. His parents are dead, so he lives with his aunt and uncle.
One day while out at a lake a beautiful woman from another planet is beamed down to earth. Kei thinks it's a dream, but the next day the woman, who calls herself Mizuho, takes over for his class, as his old teacher quit (or so his class is told). Kei soon finds out she really is an alien, and promises to keep it a secret. But then things take a turn for the stranger when, after the two are accidentally locked in an outdoor shed together and are found by the principal, Kei, in order to prevent Mizuho from being fired, tells the principal they are married (because he is 18, after all, or rather he should be). The aunt and uncle decide to make it official, and soon a marriage certificate has been signed, the rings have been exchanged, and the aunt and uncle have moved Kei's things into Mizuho's apartment.
All this happens in just the first four episodes. (No, really, I'm serious.) I've only seen the first DVD so far, so I think I may watch the rest to see how it plays out.
