Years of hard work have culminated in an opportunity to work with an experimental wandmaker to study the intersection of Healing and wand theory.
When Draco arrives, he doesn't find the wandmaker, but does find his apprentice, who happens to have ridiculously messy hair, a lightning bolt scar, and a definitely-not-charming smile.
But Draco isn’t going to let Harry Potter get in the way of him becoming a successful medical researcher, even if Potter is stubborn, hot-tempered, reckless, surprisingly gentle, has bizarre taste in music, and likes to leave his shirts unbuttoned.
