Severus was lost in the castle and he was trying to find his way back to his chambers.

At the end of a long corridor he saw a faint glow. He knew he shouldn't, but curiosity took the best of him. He stood in front of the Mirror of Erised and it showed him his deepest desire. Tears came to his eyes.

There in front of him was her, his secret love, his Hermione.

I love you too Severus. – he heard.

The real Hermione was standing next to him smiling. And he knew in that moment his second chance had just come.
