Percy was known for being arrogant and pompous so no one really liked him. Well, except for his girlfriend Penelope Clearwater who was also a prefect.

They have been dating for a while and the entire Weasley family knows because of Ginny's slip up. Including you, Harry and Hermione. You are Harry's older sister by a year and often stay at the Weasley's with Fred and George because Mrs. Weasley loves having you and Harry over

One day, at the Weasley's Fred and George were talking with you in their room when suddenly Ginny comes in with Ron, Harry and Hermione "Bad timing.. Don't do anything later, Penelope's just broke up with Percy and he's not in the best mood. " Ginny says, concerned but has a hint of grin in her face. You looked at Fred and George as mischief dawned on their faces.
