Lately this collection has been on my mind. I believe what I read was a collection of oneshots by an author, and they had some quirky stories. I only remember about three of them. I think it was only 1 volume long

One of them was about a bunch of people at war. Doing war-related stuff, then turns out the author was actually making an analogy to mosquitoes I think (I guess comparing to how fighting mosquitoes is like fighting a war?)

The other story was some people are on a tour, and the tour guide is telling about this super rich lady (princess maybe?). And some reason everything they had might seem glorious at first, but the more you think about it it actually turns out to be a very inconvenient thing. Like having a bed that was so ridiculously huge she had to walk very far or something to get to it

One other story I remember was there was a very cliche scene between a guy and a girl (maybe love interest?) and there was a misunderstanding, but rather than trying to explain stuff to them (since obviously the other character wont listen), they stuck some kinda glass tube up their nose instead and they suddenly understand the whole situation. (This story turns out to be a story that a manga artist was working on and took place in the very future where they had this kinda technology, so like a story within a story kinda thing)

Thanks for your help in advance

I read this series recently. It was really something special because it dealt with ideas and situations not often addressed in manga. And I loved it!

But I can't possibly remember its name.

Edit: I found it with the key phrase "collection of interrelated stories".

It's Terrarium in Drawer.

Yes, that's it! Thank you so much 😀
