I have a feeling that the author will make it that eunhyeok thinks Suae had a hand in the scandal at school or maybe he thought "suae was better off without him" after the rumors. But whatever bullshit reason he comes up with, I don't want Suae to get back with him even if he begs. Dohwa definitely deserves to be with someone who loves him, so unless Suae somehow falls in love with him and treats him how he deserves, I don't want her to be with himeither.
