Tomonori Iwaki is a hapless fifteen-year-old student who just had his heart broken when the teacher he had a crush on got engaged. He goes home to find that he's got a wife of his own though, even if she may look like a grade-schooler.  Rizel, a very cute girl who is apparently made of nanomachines, does her best to win her new husband's heart, and hilarity and romance ensue.
