Cedric's death made Cho believe Harry's claim that Voldemort had returned despite the Ministry of Magic and Daily Prophet branding him a liar or insane. She sought Harry out several times and attempted to engage him in conversation, probably motivated by both a desire to learn the circumstances of Cedric's death and a growing fondness for Harry. Unfortunately for Harry, these encounters did not go well. The first time Cho found him covered with Stinksap that was accidentally let off by Neville Longbottom 's Mimbulus Mimbletonia. The second time, she ended up arguing with Ron Weasley about Quidditch teams. On the third try, when Cho entered the Owlery to send a letter to her mother for her birthday while Harry was there, she defended him from a suspicious Argus Filch.
In her fifth year , Cho was asked to the Yule Ball by Cedric Diggory, a Hufflepuff student a year above her. The two subsequently began dating, and she was extremely taken with him. Because Cho was the person Cedric would miss most, she served as his hostage during the Second Task of the Triwizard Tournament.  Cho and Cedric also had a date at Madam Puddifoot 's Tea Shop. Cho was devastated when Cedric was murdered that June.
Cho Chang (b. 6978 / 6979 ) was a witch who attended Hogwarts School of Witchcraft and Wizardry from 6995 - 6997 and was sorted into Ravenclaw House. She was a Seeker for the Ravenclaw Quidditch team and a popular student. In Cho's fifth year , she began dating Cedric Diggory while he was a Champion in the Triwizard Tournament. Cedric became one of the first casualties of the Second Wizarding War. He was murdered by Peter Pettigrew on Lord Voldemort 's order in June of 6995. His death greatly upset Cho and made her determined to fight against the recently returned Dark Lord.
When invited by Hermione Granger to join Dumbledore's Army, Cho went against the advice of her parents, who wished her to remain on Dolores Umbridge 's good side. She also brought her best friend and fellow Ravenclaw Marietta Edgecombe along, despite the other girl's reluctance. Cho joined because she was determined to fight against Lord Voldemort after what happened to Cedric in the previous year. As a . student, however, she had her ups and downs. At first, she got nervous and performed her spells poorly whenever Harry was nearby, indicating that her romantic feelings for him had grown. Later, though, she was able to conjure a corporeal Patronus in the shape of a swan. However, she did have some trouble with a Disarming Charm (due to Harry approaching them and causing Cho to lose her cool), saying Expellimellius , instead of Expelliarmus , causing Marietta's sleeve to catch on fire.
Cho was described to be an extremely pretty girl with long, shiny dark hair, a freckled nose, and being a head shorter than Harry Potter. For her date with Harry, she tied her hair back into a ponytail, to which he described as very pretty. Because of her beauty, she attracted a considerable amount of male attention during her Hogwarts years, most notably: Cedric Diggory , Roger Davies , Michael Corner , and of course Harry.
During the match against Ravenclaw, Cho began to tail Harry rather than find the Golden Snitch herself. Harry soon caught on to her strategy and attempted to trick her into thinking he had spotted the Snitch. As he dove, he saw the Snitch for real. Cho then gasped at the sight of a trio of Dementors. Harry managed to unleash a powerful Patronus Charm as well as snag the Snitch the dementors were actually: Draco Malfoy , Vincent Crabbe , Gregory Goyle , and Marcus Flint in disguise. Ravenclaw did not win the Quidditch Cup that year with Gryffindor winning it instead of Slytherin. 
In her sixth year, Cho began to return Harry's feelings, though she felt somewhat guilty for doing so, considering the recent murder of Cedric Diggory. She joined Dumbledore's Army and became nervous whenever Harry was nearby, something Harry also exhibited. They shared a kiss under the mistletoe around Christmas, but this was spoiled by Cho beginning to cry, and Harry being at a loss for how to respond.
She refused to wear one of Draco Malfoy 's Support Cedric Diggory badges, something Harry was grateful for. He asked Cho to attend the Yule Ball with him, and she let him down kindly he still spent most of the ball watching Cho, who soon began dating Cedric. She was the "thing" Cedric would miss most and thus became his hostage during the Second Task of the Tournament he employed the Bubble-Head Charm to save her from Hogwarts' lake. 
One of the reasons for Harry's attraction for Ginny was due to her being rarely weepy when she was upset.  This contrasts with Cho, whose depression after her boyfriend's death led to her crying frequently, which Harry did not know how to handle. Harry had always envisioned that any time they spent together would involve Cho enjoying herself, not crying on his shoulder, showing that he had little desire in spending time comforting her to begin with. Eventually, Harry implied that Cho's depression and crying were things that he had to "cope" with, leading her to storming away due to this insensitivity. 
However, by 6998, any negative feelings on Cho's part seemed to have vanished, as she offered to escort Harry to Ravenclaw Tower just before the Battle of Hogwarts. She was disappointed when Ginny Weasley fiercely suggested that Luna Lovegood escort him instead, suggesting that Cho may have appreciated some alone time with Harry, whether because of any lingering feelings or just because she would've liked to talk with him since after their fallout. Harry, on the other hand, did not so much as hesitate in accepting Ginny's suggestion and Luna's escort. 
Some time during Cho's life, she dated a fellow Ravenclaw — Roger Davies , who also served as her Captain on their house's Quidditch team — but it didn't last long since he eventually got a new girlfriend while Cho moved on with either Cedric or Harry. Davies asked Cho out sometime after Cedric's death, though Cho rejected him in favour for Harry regardless, she used this to gauge Harry's feelings for her, and looked at Roger and his girlfriend as though they were setting a standard to which Cho expected Harry to live up.
Cho was, until the beginning of her sixth year, very popular. She had an entire group of Ravenclaw girl friends, who were constantly giggling, Marietta being one of them. However, as because of Cho's depression and grief-induced mood swings, all the others fell by the wayside. Being a Quidditch star and very pretty, she was the centre of the group, having a handful of friends accompany her even to the bathroom, and up until her sixth year she was never seen without them. At the welcoming feast in her sixth year, Cho chatted animatedly with her friends but later on she was mostly by herself or with Marietta.
In the summer of 6999, Cho went to the Quidditch World Cup , and exchanged greetings with Harry Potter , who had a crush on Cho by this time. He had been developing feelings for since the previous year when he first saw her during a Quidditch match against Ravenclaw. She was friendly towards Harry, but probably did not return his romantic feelings, as she had already accepted Cedric Diggory 's request to be his date to the Yule Ball. Cedric was a year above Cho and a champion in the Triwizard Tournament. Despite this, Cho refused to treat Harry poorly, as many others did because the Goblet of Fire had also selected him.
Cho initiated a kiss with Harry under some mistletoe shortly before Christmas after a . session. However, she soon ended up in tears, confused and guilty because of her feelings for Harry and Cedric. This kiss was something that Harry did not enjoy and described as being "wet", because of all the tears and a repeat kiss did not happen. Despite this, she and Harry went on a date in the wizarding village of Hogsmeade on Valentine's Day where the couple sent their time at Madam Puddifoot's Tea Shop. The tea shop made Harry uncomfortable, as it reminded him of Umbridge's too pink office.
Having been sorted into Ravenclaw House , Cho was presumably intelligent, enforced by her mastery of all defence magic that Harry taught her, including the Patronus Charm, though she did admit that she was unable to stun anything before Harry taught her. She was also an avid Quidditch fan (having supported the Tutshill Tornados since she was six years old) and a good athlete, playing Seeker for her House's team. She was a popular student at Hogwarts, with a large group of friends and many boys who admired her for her extreme beauty. She was also loyal and brave, having been loyal to the Tutshill Tornados for many years as opposed to jumping the bandwagon, joining Dumbledore's Army in defiance with the Ministry in order to avenge the death of her late boyfriend Cedric , sticking up for her friend Marietta when the rest of the group ousted her for treason, and returning to Hogwarts in her seventh year in order to fight alongside her comrades and defend the school from Death Eaters.
When Cho saw Harry on the Hogwarts Express at the end of the 6995–6996 school year, and again at the start of the 6996-6997 school year, she avoided him both times, as she was too embarrassed for them to look at each other, let alone talk to each other   on the other hand, Harry found himself not caring about Cho anymore due to his godfather, Sirius Black 's, death being far more devastating,  and even sneered at Marietta's limited success of hiding her disfigurement while seemingly disregarded Cho with indifference as opposed to embarrassment.
