Residual (COMPLETE)

When Harry Potter is brought into St. Mungo's with a curse that should not exist, it's only natural that he is assigned to the Senior Curse Analyst in the Spell Damage Division, Healer Draco Malfoy.

Only, this curse has turned into something intelligent, reactive, and dangerously personal. What begins as an unstable magical injury becomes something far more intimate, binding Harry's survival to proximity, memory, and the one person he should never have been tethered to again.

Draco and Harry do not trust each other. They do not even like each other.

But the curse does not care.

As the line between healer and patient dissolves, so does everything else they thought they knew about the war, about themselves, and about what it means when magic remembers too much.

Some spells do not just hurt you, some of them choose you.
