I was definitely emotionally invested. I started getting twisted up when Hedwig died, and I sobbed through Dobby's death and burial, and when I finished crying for myself over Fred's death I started sniffling for Koshie's sake.

And slash fan that I am, I still knew OBHWF was the true canon, so the epilogue didn't bother me in the least. I'm just sort of glad she made it 19 years later, instead of giving us the double wedding.
