This was beautiful. I didn't expect the ending and didn't expect it to be so painful all over. I am sorry for both Ginny and Albus Severus for loving and never getting true recognition from the (Malfoy) men they loved.
Funnily enough my only complaint with this story was that it didn't feel like Snarry. It was so much more and calling it Snarry would be almost an offense to all the other characters that were part of it. I gave it all 9's for you did excellently with your prompts and genre and I enjoyed (suffered along with the characters throughout) the story, but if I had to rate it for Snarry-ness it'd get 5 maybe 6. Still I think it is a great fic.
In my mind I hope that at some point Albus Severus found another love, someone who deserved his devotion, just like his father found Severus. I loved your idea that Harry shared his live-force with Severus and I am not sure if Severus knew. The last words of Severus' could have been knowledge of that or simply repetition of something Harry has told him as a confirmation of his love.
I even hope Ginny found happiness. And I guess I am nasty for hoping that Scorpius never lived to overcome Albus Severus' loss, but Malfoys are resilient and would never admit to their true feeling so maybe he never let it bother him.
Duh, I can probably go on and on, with these stupid thoughts but that would be rather pointless. I loved it. Thanks for this fic.
