They're really going overboard with the foreshadowing or whatever you'd call it. I mean, all that happens on the other side, ever, is that the brother's finding a way to come over, pretty much just reiterated like 5 times now. It would probably be worse eventually if I wasn't annoyed by it but bought into the desperate hype they're trying to generate because you just know it won't be anywhere near worth the buildup.
@biznizz Its title is "The Matter Regarding the Female Knight Who Came to Live With Me in the Countryside" and it has the slice-of-life tag with all slice-of-lifey covers. You're at fault here for expecting anything different, not the story.
