This has one of the worst titles I've seen, even with LN standards, but the content is okay enough
Seriously, who thought "My Twin Sister Was Taken As a Miko And I Was Thrown Away But I'm Probably The Miko" was a good title? I know that the LN market is oversaturated, so they have to put the entire summary in the title, but come on. We already can infer the second part because of course that's the case. You can't judge a book by its cover, but that is definitely why I actually read this
