Cho Chang

Cho Chang (born c. 1978 or 1979) was a student at Hogwarts, sorted into Ravenclaw House. She was a Seeker for the Ravenclaw Quidditch team.

Fourth Year
Harry Potter first met Cho during his third year (her fourth year) during a Gryffindor-Ravenclaw Quidditch match, in which Cho and Harry were playing Seeker against each other. He noticed she was very pretty and she made his stomach "feel funny". The only other notable interaction between them that year is when Cho wished Harry good luck before the Quidditch match against Slytherin and Harry went bright red.

Fifth Year
During Harry's fourth year, his crush on Cho developed further. They exchanged greetings at the Quidditch World Cup, and he later works up his courage and asks her to be his date to the Yule Ball. However, Cedric Diggory, one of the other champions of the Triwizard Tournament, has already asked Cho out, and the two of them end up dating. Nonetheless, Cho is still kind to Harry - for example, she refuses to wear one of Draco Malfoy's "Support Cedric Diggory/Potter Stinks" badges, a fact for which Harry is grateful. That July, Cedric is murdered by Peter Pettigrew (on Lord Voldemort's orders).

Sixth Year
At the beginning of Harry's fifth year, Cho surprised him by seeking him out several times and attempted to have a conversation. Unfortunately, for Harry, these encounters did not go well. The first time, she found him covered with Stinksap that was accidentally let off by Neville Longbottom's Mimbulus Mimbletonia, and the second time she tried to talk with Harry, she ended up arguing with Ron Weasley about Quidditch teams. On the third try, when she happened to enter the Owlery while Harry is there, she defended Harry from a suspicious Argus Filch.

When invited by Hermione Granger to join Dumbledore's Army, Cho (who made her fellow Ravenclaw friend, Marietta Edgecombe, go along) went against the advice of her parents who wished her to remain on Dolores Umbridge's good side. Cho joined because she is determined to fight against Voldemort after what happened to Cedric in the previous year. As a D.A. student, however, she had her ups and downs. At first she gets nervous and performs her spells poorly whenever Harry is nearby; later though, she is able to conjure a corporeal Patronus in the shape of a swan.

Cho initiated a kiss with Harry under some mistletoe shortly before Christmas after a D.A. session, and on Valentine's Day they went on a date in the wizarding village of Hogsmeade, but Cho's grief over Cedric's death, her ill-founded jealousy over Harry's friendship with Hermione (who, ironically, tries to advise Harry on how to handle girls), and Harry's overall inexperience with girls soured the experience.

When Marietta betrayed the D.A. to Umbridge, she was afflicted by the hex performed by Hermione on the piece of parchment, signed earlier by all members of the D.A. The hex made purple pustules spell "SNEAK" across her face and they cannot be removed. When Harry scorned Marietta for the betrayal and Cho defended her, irate at what she considers Hermione's "dirty trick", Harry and Cho's relationship went downhill.

Seventh Year
Harry caught a glimpse of her during the ride to Hogwarts on the Hogwarts Express at the begining of the her seventh year, but she hid back in her compartment with Marietta. Harry later mentioned in a conversation with Ron that the two of them just "fell apart".

After Hogwarts
Despite a soured romantic relationship with Harry, Cho demonstrated her loyalty by reuniting with other members of Dumbledore's Army to join the battle against Voldemort and the Death-Eaters when they attacked Hogwarts. She appeared amicable and friendly with Harry. She also seemed disappointed when her proposal to lead Harry to the Ravenclaw Common Room in the search for the Horcrux was fiercely denied by Ginny, which indicates that she has no hard feelings for Harry anymore.

Cho later married a Muggle.
