Lol you just reminds me of her mother, haru really is an enigma coming from her mother, she just too pure or just too dense when coming to it, even thought that her mother is doing it with everyone, it will be interesting if haru get awakened later in the chapter.
Also I'm agree with everyone here, eury isn't unattractive, she just lost the opportunity for getting the right partners, maybe she a little bit picky with her choice, if I'm given a choice to choose between eury and haru it will end up with eury every single times, maybe haru win for the body but she still a kid for me.
