Yuzaki Nasa is a third-year middle schooler who has always had an inferiority complex tied to his strange, spacey name, at which everyone always seems to snicker. That led to him becoming an overachiever on the fast track to adult success…until one chilly winter night he spots a girl and falls in love at first sight.
That sudden surge of love is so disorienting, he walks straight into the path of a passing truck, which strikes him. However, he wakes up to find he’s not dead; the girl saved him, and looms over him backlit by a majestic full moon. As she turns to leave, leaving the truck driver to call an ambulance, she appears to him to be returning to that moon, like Princess Kaguya.
Rather than accept that like Kaguya the girl must return to the moon, Nasa makes the most of his post-accident adrenaline and follows her to an enclosed bus stop. She’s impressed he was able to even move, and gives him her coat to stay warm before bidding him farewell once more.
But Nasa won’t let it end this way. Even with two broken legs, he gets up and chases after her once more, declaring his love and asking if she’ll go out with him. She agrees that they can be together…but only if he’ll marry her. Since Nasa is already in love (and adrenaline’s a hell of a drug) he quickly agrees before passing out.
He wakes up some time later in the hospital, and doesn’t hear from the girl for years as he completes middle school but declines to pick a high school and enters the workforce as a konbini clerk. He turns eighteen and gets an apartment on his own.
It would seem that a combination of his injury and the girl’s tacit rejection-by-absence cost Nasa a more prosperous life, but only until his doorbell rings. Who could it be at the door at this hour? Why, Tsukasa, who by night’s end will be his lawful wedded wife!
There’s a charming matter-of-factness to Tsukasa’s interactions that border on alien-or-robot-like inhumanity, but I preferred to take a less cynical tack throughout my viewing. Suffice it to say, Tsukasa is ready to honor their hasty agreement from years ago to wed, because she offered it and he accepted.
As she suspected, Nasa isn’t one to back down from his word; indeed, upon her sudden unexpected return to his life he’s compelled to recite his credo “I’ll go faster than light before NASA!” In other words, while his professional ambitions may have been dashed as an indirect result of meeting her, in exchange he gets to marry an exceedingly cute young woman. It’s a fair deal!
There’s also a sense of quietly brewing vicarious excitement as the process gets realer and realer, first with the filling out of mundane forms, then the visit to the ward office (open 24 hours for weddings), to the moment the two are officially married and simply holding hands for the first time is more than enough excitement!
Setting aside the possibility of this work’s creators intending to deliver a not-so-subtle message to the youth of Japan to get married and have kids already!, the ward official is absolutely right that young love and marriage is indeed portrayed as beautiful, joyful thing.
There’s still the big questions like why exactly Tsukasa is so okay with suddenly marrying a guy who fell for her at first sight, why there was zero contact in last couple years, and what exactly the new Mrs. Yuzaki had to “take care of” on her own before heading home with him. But for now I’m content to revel in the elegance of two hearts finding one another.
P.S. The OP absolutely whips. I love how it starts so simple and bittersweet then captures the chaotic whiplash of suddenly sharing your life with someone.
