you were in potions class and honestly you weren't paying attention, you were lost in your thoughts until Snape asks you to smell the potion

"I can't, Draco's perfume stinks and it won't let me smell it"

Draco glared at you in disgust and didn't stay silent, he stood up quickly

"It's your perfume that stinks everywhere"

he said angrily until Professor Snape says that it is "amortentia" and both of you look at each other in surprise as some students laugh
