My cat threw up right next to me while I was reading this. He knows what's up.
I also was confused why two people would need that many rooms, but I had re-read the 3rd chapter right before and remembered Yuna saying that they should look for 2 rooms. Maybe it was just some inconsistency by Morinaga? I suppose we'll find out when they actually find a pet friendly apartment. Or alternatively, if they are thinking long term residency, it's always better to buy a little bigger if you can afford it.
As alluring as the thought of a bed in the kitchen is, I shudder at all those crumbs. Crumbs where crumbs don't belong.
