Something was always missing (слэш)

After the war, Severus Snape does the unthinkable: he erases Harry’s memories of their love to set him free, believing himself too broken, too old, too guilty to be what Harry deserves. He endures three years in Azkaban, clinging to the memory of love that Harry can no longer return.
When an investigation birings Harry back to Snapes cottage, pieces begin to fall into place - and love, though buried deep, proves stubborn.
“I just wanted you to be happy. You deserve the whole world,” Severus whispered.
“But you,” Harry said, voice breaking, “you are my world.”
