If this was written as satire, it is one of the funniest ones ever written. If not, it is the laziest story ever made. The plot is non-existent, the characters literally not even having names. Our protagonists literally randomly bump into each other and immediately decide to get married. This sounds like I'm exaggerating, but I'm not. They literally just look at each other and it's like they're being mind-controlled into marriage for literally no reason whatsoever. The mangaka of this ones-shot has written several series that seem to have at least decent reviews, which would make it strange for her to write this onan absolute whim. I can only conclude it is a ridiculously and absurdist mockery of Shojo in the same way "Destroy!" by Scott McCloud is for Dark Age superhero comics. In that case, it deserves a 10/10
