Draco / Drarry

After the war, Potter almost immediately became an Auror along with Ron. He'd already been protecting the magical world from evil, so his job literally defined his life, but he'd also longed for this at school.
Potter got the Malfoy family off the hook, with the exception of Lucius, for saving himself. Perhaps it was the adrenaline, stress, and emotions that took him a long time to recover from. Or perhaps it was truly because of their actions. He didn't want to dwell on it.
Later, of course, the brown-haired man learned that Draco worked as a Healer. Yes, he was still adept at potions and spells at Hogwarts, even to this day.
Healers were recently introduced to Auror missions, and they were protected like the apple of one's eye, as they often wore completely sterile clothing. Not all missions left the Aurors with the strength to heal their comrades, and spells and basic restoration potions didn't always work.
The Auror wasn't worried: they had a designated Mediwizard, and he'd never let them down, but when he left for Australia to find some ingredient for a terribly rare potion, his squad was assigned... Malfoy. He looked the same, though... even better. He'd also grown his hair out. Always impeccably dressed, he still dressed only in silk and high-quality suits: they'd left him some of the fortune, but he hardly took it, leaving it all to Narcissa. The healers made good money, and he was alone, didn't really need anything, so he'd been living it up on clothes. Although Slytherins, even former ones, were nothing compared to "needless ones." Harry gritted his teeth and went on missions. He didn't want to leave his job, even for a short time. And when they were told that Draco would remain their permanent Mediwizard due to the squad coup, Potter nearly lost his mind. It was becoming unbearable to see that arrogant face.
