I don't want to read the novel, but I'm curious:
Is this going to be one of those mangas where the start of the actual relationship is the end of the story? Like the final chapter is going to be the two of them deciding to make their "trial marriage" permanent and that's it... the end?
I hope not. I want actual marriage and real husband/wife hijinks to follow the "fake couple" hijinks. Since it's clear they obviously love each other it's not like they need to milk the drama up to the decision point.
