Between Shadows and Desire (слэш)

During his fifth year at Hogwarts, Harry makes an unexpected request: extra Potions lessons with Professor Severus Snape.
What begins as a reluctant agreement soon turns into something far more complicated. Long evenings in the dungeon classroom bring sharp words, reluctant respect, and a tension neither of them quite knows what to do with.
As the lessons continue, the space between teacher and student grows increasingly fragile. Glances linger a little too long, conversations drift beyond brewing instructions, and Harry begins to realise that the most difficult thing he may have to learn this year has nothing to do with potions at all.
