Did u not read the books? Cho is like this popular girl that all the guys like! Similar 2 a cheerleader at most schools! So of course Harry had a crush on her n they kinda went out in the 5th book but only b/c Cho was trying 2 get info about cedric. Who was her boyfriend who died in the 4th book! Harry at the end of the 5th book decided that he no longer liked cho n that she was annoying! Thats b/c Rowling is setting him up so he can go out w/ Jenny! every1 knos that! but i thot I was the only 1 who that that he shud hook up w/ Jenny! DUH!
