it's not really an emotion i suppose, but "Pleading".
i don't want things to end like this. They had a great thing going, but somewhere along the way, things changed. And you desperately want things to go back to the way they were, happier times, and on some level, you're holding out hope that they will, but the only thing that keeps that hope alive is a blind faith or a gut feeling. so yeah, there's a pleading (to Fate or who knows) for one more chance. just one last chance that things could work out..
(lol, sounds like i'm talking about a relationship)
