Were We Blind?

Three years after the fall of Voldemort, after finding a golden friendship overriding puppy love, Ron and Hermione found things were best kept the way they had always been after dating for six months.
Now Ron is happily married to Luna Lovegood and still on the same terms with his soul best friends.
Ginny's heroic death in the War of Hogwarts leaves both Hermione and Harry alone in terms of soulmates. Or was there always something there between them, overlooked by Ron and Hermione's long term teenage love-hate relationship?
Please don't hate me for killing off Ginny.
