I think people who have read this focus too much on the mpreg. The mpreg is barely there. What we should focus on instead is the “there was only one bed” trope. It happens all the time in this series, but only with these two because they never even consider other options, like the couch. It’s not even that they have to share a room in the first place either, they just keep offering to.
Actually, at that point, does it even count as “there was only one bed”?
