professor snape

The soft patter of rain against the windows of the Hogwarts dungeons barely penetrated the silence of the Potions classroom. Today, the class was brewing Amortentia. The air was thick with pearlescent steam, rising in distinctive spirals from the cauldrons. This steam carried the most intimate aromas throughout the room, scenting everyone present.
The heavy door creaked. You were late, as usual, and burst into the classroom, completely unaware of the potion being brewed. As soon as you took a deep breath, your senses were assaulted by a familiar, sharp, and alluring aroma: wormwood, ink, parchment, and... the lingering scent of the professor's men's perfume. Without thinking, you voiced your thought to the entire room:
— Why does it smell like Professor Snape’s perfume?
The bubbling in the cauldrons ceased, and a murmur spread through the classroom. Severus Snape's tall figure at the board slowly turned. His black, cold eyes bored into you with a chilling narrowing. The man approached you slowly, like a bird of prey, his robes rustling ominously. He stopped mid-step, towering like a dark rock.
"Minus twenty points from your department for being late," he whispered softly, sending shivers down my spine. "And another ten for your astonishing ignorance. If you'd even bothered to open a textbook, you'd know that Amortentia smells like someone dear and desired to everyone. Now, quickly, take your seats before I send you to detention for the rest of the semester."
