Summary:
Sanamund was not very fond of Professor Slughorn, although he was undoubtedly favored by the professor.
Students don't like a teacher who treats him well. Especially when this professor also serves as the Dean of Slytherin, it is best not to reveal such thoughts to others, not to mention that what Professor Slughorn does is just to think more about himself. As the prefect of Slytherin, Sanamund is also well aware of this.
The young man always smiled gently and perfectly completed all the errands given to him by his dean, whether it was legitimate or the professor should have done it himself but was always unable to do it because of pineapple preserves and other things. For example, go to the orphanage to inform a child who does not know his identity as a wizard to enter Hogwarts.
