Harry Potter Character Guide
Cho Chang is a Ravenclaw student one year above Harry, and is the Seeker for the Ravenclaw Quidditch team. She is best known for being Harry's first love interest, is described as being very pretty with long dark hair and is frequently accompanied by a group of giggling girls. In Goblet of Fire, Harry's crush on Cho intensifies and he works up the courage to ask her out to the Yule Ball, one of the necessary events in the Triwizard Tournament, but Cho apologizes and replies that she had previously accepted Cedric Diggory's offer. Nonetheless, Cho is still kind to Harry, much to his relief, and she refuses to wear one of Draco Malfoy's Potter Stinks badges. She and Cedric maintain their relationship until he is murdered by Peter Pettigrew on Voldemort's orders.
Cho is one of the first students to believe Harry's declaration of Voldemort's return in Order of the Phoenix, and when invited by Hermione to join Dumbledore's Army, she joins because she is determined to fight against Voldemort and avenge Cedric's murder. Cho initiates a kiss under the mistletoe with Harry after the last Dumbledore's Army session before the Christmas holidays. Harry and Cho go out on a date on Valentine's Day, but her sustained grief over Cedric's death, her jealousy over Harry's friendship with Hermione, and Harry's lack of knowledge about girls all make for a miserable experience. Their relationship ends when Dumbledore's Army is exposed following Marietta Edgecombe's betrayal of the group to Umbridge. Cho defends her friend's actions by saying that Marietta simply made a mistake. After the last Quidditch match, Cho begins dating Michael Corner.
In the series finale, Cho demonstrates her loyalty to Hogwarts when she returns to join other Dumbledore's Army members in hiding in the Room of Requirement prior to engaging in the Battle of Hogwarts; Harry and Cho, united by a common cause, appear on amicable and friendly terms. She shares with Harry the little information known about Ravenclaw's diadem (one of Voldemort's Horcruxes).
