Louise

"She will definitely go out with me now."

- Unidentified boy about Louise

Louise was a student who attended Hogwarts School of Witchcraft and Wizardry during the 1990s. During the 1996-1997 school year, Harry Potter was asked by another student to make a potion for the student, as Louise had been asking for it. Harry successfully brewed the potion and gave it to the boy, who was delighted and claimed that Louise would "definitely go out with me now."

Behind the scenes
It is possible that the boy lied about the potion and that it was an Love Potion.
