I think that Rent-A-Girlfriend should happen. Consider it as our canon event. Let that manga as a learning experience and something worse might happen if Rent-A-Girlfriend didn't exist.

I really wish this isn't one of those "japan win because japan author". Because there are mangas with the same genre/theme that subverts your expectations.
