now that u mention it, after that bed/blanket incident in keima house, ayumi did say at the bus "it can't be helped,it can't be helped"That's why she felt horrible. One part of her was happy that she was removed of a rival in love, but for the most part she felt angry at Keima since it was her bestfriend they were talking about.
so how did u think this gonna turn out for ayumi ?
