@me474 Not sure what you want me to say. I already agreed with you that it's probably inevitable. That doesn't make it any less of a spoiler though. We could read 100 isekai harems with this sort of thing being hinted at in their summary, make it to the 99th with all of them going exactly as you and I both suspect this one will, but until we read that 100th one it's still up in the air because that author could actually subvert expectations. They do that sometimes because they realize we're expecting things and they want to try something different for whatever reason.
Also, I don't care that it's a spoiler myself. But by definition it is one, whether you want to say it's only a light one or whatever, if it it does reflect how the story will turn out past what that summary mentioned it's a spoiler. One that some people will want to have and some would prefer not to, while I don't really care either way. Other than being slightly amused that there is a spoiler that group A would always like to know about while group B never wants spoilers ever, and groups C-Z run the spectrum between those such as me not really minding it or someone liking this specific type of spoiler not disliking others.
