A Very Drarry Story

Harry and Draco's future children, Albus and Lucy, die and are reborn as their parent's younger siblings.

Albus is now Claudius, Draco's younger brother...
and Lucy is now Damien, Harry's younger brother. Yeah, somehow the gods mixed that up.

But now they have a new problem. When Harry and Draco were younger, they did like each other, and Draco confessed to Harry after Voldemort was defeated, soon after they were married, adopting Albus and Lilly 3-4 years later.

It seems, however, something is off. This Draco and Harry have no indication of romantic feelings at all!

Draco is a rude Slytherin bully, but underneath the surface, he has a heart and would do anything to protect those he loves.

Harry is just like his past self, but is much more closeted than before, as well as wants nothing to do with Slytherins or Draco. Harry also has a GF, a girl named Cho, who was supposed to be Harry's unrequited crush.

Will Albus and Lucy change the timeline for the better?
Or will they fail, and Cho the Hoe will still be able to date Harry, Draco will still mask his emotions, and Harry will still be closeted/repressed about his sexuality?
