no, they didn't know the real reason because Ash didn't disclose why they broke up, I think it's to save Hazel's image because he's for the streets and if their friends knows, then their entire circle from college would also know, I think that was Ash last "mercy" towards that cheating hoe
so are his friends just spreading lies and rumors left and right??? at his fiance's house???? im more mad at them than anyone
