Garreth Weasley, Seventh-Year.

Potion's Class—a place where students learn and create potions for all kinds of aliments and injuries, romance and death—a crucial class, one of which you excel in. However what you don't excel in, is knowing when to question your friends and when Garreth asks you to test a new potion of his—not stopping to question it, your first mistake.

Turns out, Garreth's potion failed and has caused you an intense and unforgiving aphrodisiac episode—was it a mistake?
