Hannah: Harry and Ginny were being teased at with the song "Hary and Ginny sittin' in a tree.." because people thought they belonged together. They won't admit their feeling for each other, though. Hermione and her boyfriend, Ron, made a plan to stop that. Hermione told Ginny to walk into Mr. Binn's empty classroom at 5:00, and Ron told Harry the same thing. Soon, they were both alone in the classroom, and Hermione locked the door with a spell. Ginny and Harry were locked in an empty classroom, alone.
