I think I should express some annoyance about all the series that use romance as a hook-up for readers, then side-line the romance aspect so they can write about what they really want, and once the author finishes the story he wants to tell, come back to conclude the romance storyline, almost like and afterthought.
I won't though, because I read isekais and it's the same thing, except most isekais aren't as satisfying as this cute manga about alien girls eating food. It was a good read while it lasted.
