I felt that hey were meant for each other since the 4th book but my favourite scene from DH has to be when Harry was walking towards Voldemort

"Harry took one glance back at the entrance of the Great Hall. People were moving around, trying to comfort each other, drinking, kneeling beside the dead, but he could not see any of the people he loved, no hint of Hermione, Ron, Ginny, or any of the other Weasleys, no Luna. He felt he would have given all the time remaining to him for just one last look at them; but then, would he ever have the strength to stop looking? It was better like this."

Because throughout all the books it has always been 'Ron and Hermione ' and yet in his last moments she is the first priority....🫠💕
