An Antidote to Regret (слэш)

When Harry wakes in the past, he’s determined to change everything - to save lives, stop the war before it begins, and rewrite the ending for a boy who was never given a chance. But building trust with a young Severus Snape is more than strategy - it’s friendship, and maybe something Harry never expected to find.
Together, they’ll hunt Horcruxes, challenge destiny, and find healing in a world not yet broken.
