That too. And there's also another way to look at it : if she just accepted him, that just wouldn't work, because it's about feelings, not a business transaction. Love confessions in general, imo, only work if both sides already have feelings, or the receiving side is ready to accept anyone. But maybe her answer opens the way to an actual relationship later on : now the slate is wiped clean and he was upgraded from admirer to colleague. Then if they go through a few things together, who knows what might happen...she doesn't want feelings, but love doesn't follow desires.
