This is super cringe, used to be decent before Haru and Karen became a couple, now it's a complete shitshow
Author fucked the story up as soon as he had Haru sent to that place for zero reason. I'm serious, there's absolutely no reason Haru needs to be on that island, they could've literally sent any female from the Imperial Knights or sent Karen herself. But logic and reasoning must be the author's kryptonite
