hey, i was wondering if you know this one hs fanfic i read but haven't been able to find since. i think it's called bitter (i could be wrong) and it was where the female mc and harry were childhood bsfs then harry went on x factor and got famous and started hating her for a reason that we and the mc don't know. she was irish (i think) and her dad was an abusive assh0le, also i'm pretty sure her childhood bedroom was painted purple which was significant for a reason i don't rly remember. harry and niall are bsfs after he becomes famous and are both assh0les to the female mc cause she apparently did smt to harry. what ends up happening is harry's old piano teacher who's name started with a d i think messed their (harry and the mc's) whole relationship up.
sorry for that huge long random description (that might sound really generic), i just wrote down everything i remember. pls if you can help me find it that would be amazing it's one of the best ffs i've read it was so good thank youu!!
