I've said this before, but I think that charry (cho x harry) could've worked out if the author tried to make it, but after GOF she wrote that they had went on a date and realised they didn't like eachother that way. I interpreted this differently though
my aro little brain thought this: cho knew that 1: Harry liked her, and 2: he saw cedric die. she took advantage of this and tried to date Harry so she could figure out more about cedrics death. think about it, almost every time they spoke it was "if CEDRIC knew all hat stuff" or "did CEDRIC say anything about me before he died?"
this is certainly a wierd interpretation of Harry and cho's relationship with her playing detective and him as the witness. so ye cya
