Task: Question Answering
Input (English): Context: It did n't matter how much time she did spend with Severus , she still wanted more . More of his time , more opportunities , more anything that had to do with him . It seemed counterintuitive , but it was the honest truth . Hermione did n't realize how true until September came around once again , and Severus 's duties at the school sharply diminished the time they had together . Hermione understood , of course ; she knew how hectic the first days were at Hogwarts from her own years ' experience , but she still missed him when it seemed like their schedules would never cross again . It was a few weeks into the new semester before everything calmed down to a point where they once again had their evenings free for each other . 
Question: Why was Severus so busy ?
Output (English): Severus had a lot going on with school .
