There is no mother-in-law in this story. No, mother-in-law is the nickname Mashiro earned when she was younger because the other girls didn't like the way she'd nitpick everything, which in turn ties into a negative mother-in-law stereotype. This does, in some ways make the one-shot a bit odd of a read, yet it ended up being quite enjoyable. For those who enjoy romances where opposites attract, this particular piece will be a quick read. Still, if the readers think it will be a run-of-the-mill romance with absolutely no development where the opposite traits are Mashiro and Kobato, the beginning is simply the setup.
