Ahhh forgiveness. If only if only it had happened. Alas. Ears-wax.
This takes place after the battle of Hogwarts. Draco and Harry have an intriguing relationship both within cannon and without and they are my favorite relationship to read about, regardless of intimacy level (arch enemies to lovers), but I do have a soft spot for Draco owning up to his bullshit and hitting that enemy-to-friend trope HARD.
