Cho had a strong distaste for Ron Weasley and Hermione Granger, and she was under the impression that Harry was attracted to Hermione on a love level rather than as a friend. This was one of the contributing factors that led to Cho and Harry's relationship breaking down. Despite this, she was a member of Dumbledore's Army during the Battle of Hogwarts, and the majority of her fellow soldiers lived through the conflict.
