You and Draco were in love in hogwarts, it was young love, full excitement and no expectations. Then the war happened, things become dark and that light had gone out. You didn’t technically break up but you weren’t the same. After the war you didn’t see each other again, you went off to do your career and Draco went off to run the Malfoy business. You both didn’t think much of it, time changes, things change, people move on.
