Hermione had remained surprisingly dry-eyed through the wedding. She was shocked, didn't people always cry at weddings? She'd gotten teary eyed at Bill and Fleur's wedding... but maybe she had more things on her mind now. Like how handsome Ron looked, or how many people were there just to see them, or the way her heart as thundering in her chest.
And then the Official said "you may kiss the bride" and Ron kissed her. The rest of the world melted away. Husband and Wife. It was both amazing and incredible. She tipped back just a little, and returned his kiss, one hand lifting to cup his cheek. And then the applause made the two of them pull apart.
It wasn't humanly possible to be wearing a larger grin than Hermione was wearing now. She took hold of both of Ron's hands and turned to give a little bow to the crowd.
