After the Battle of Hogwarts, students returned to finish their studies, including Draco Malfoy. After completing his studies, Draco decided to ignore his father and become an Alchemist. One afternoon, Draco had arrived at Snape's mansion to help him with some potions. While they were talking, the doorbell rang and Severus told Draco to open it, as the person had arrived for his potions. Draco opened the door and was surprised to see the person in front of him.

"Granger," he says softly.
