Both mangas involve a main female character who has a problem with their heart, either she can't be around boys(HND) or it's been taken away and now she must search for it (SLH). They are both romances and in both of them, the main fem is powerful and is being "hunted" in a sense. Of course the stories are different, but both a good read :)
