With that being said, I don't think I'll be coming for more. Besides being uncomfortably pro-nobility, which it always was but it kinda escalated here, it's also falling more and more on that specifically Japanese style of humour where the same thing happens over and over and over again but it's supposed to be funny (and often the same thing is person A being horrible to person B and always getting away with it, or two people being horrible to each other in turn), something that I never managed to enjoy.
This is mostly due to a shift in the cast - Mary, Adi, Alicia, Patrick together are playful and silly. Mary, Adi, the twins and Roberto together tend a lot more towards mean, one-sided, and one-note.
E.g. Alicia glomping Mary is a constant, but it leads to different resolutions or new banter. Meanwhile, the twins secretly not being interested in taking over the house is a joke that always has the same resolution (Mary is too stupid to notice or gets distracted), felt old in the previous volume already, and was the most common joke in this volume too.
It's too repetitive for me. The joke of "it's a tourist brochure with a stern looking cover" alone got how many repeats, six? A dozen? More?
