((Gosh dangit Jelly, your trying to kill me aren’t ya? *drowning in all the fluff* X3 Thanks for requesting))
France: Overjoyed. The emotion would flow out of him the most naturally, and he could practically make the room glow with the emotion, just as much as your beauty did. Of course the many ways that this expression can be shown are varied, but his would most definitely be a smile on his face and tears in his eyes. Today he would finally have a dream come true, and that would be to spend his days with you as more than just a “maybe”.
England: The moment he saw you walking down the aisle, regal and queen-like, he’d be filled with such a happy pride. The kind that brings butterflies to one’s heart, and makes them feel like leaping for joy. Of course he’d be a bit of a sap and try hard not to blubber in front of everyone. This would be the happiest day of his life, and the start of a new adventure. For the both of you.
Russia: That little smile he always had on his face wouldn’t be little anymore! It would be big, wide, and true. The moment he sees you walking down the aisle would be one he’d never forget. He’d reflect on how lucky he was to have found you, and that now you would become on with him. All he had ever really wanted was a companion like you. He’d surprise everyone by shedding a few tears, and not hurrying to wipe them away.
America: He’d definitely pull a Tamaki Suoh and blush loudly, making him a bit of a nervous wreck. One thing that never failed to catch him off guard was your beauty. It was always so disarming that sometimes it was all he could do to not stare. On this day in particular, as you walked down the aisle, there was only you. Nothing else would matter to him.
China: Well to say the least, he’d feel very honored. Honored that you chose him after he gave you his heart since the day he met you. He’d be in that state where he’d want to cry, but something would keep the tears at bay until the moment the two of you were pronounced as “Husband and Wife”.
Italy: This would be another one of those rare moments where he could become serious. Everything about him would be calm, as everything around him would be surreal. And the moment you come down the aisle, it would all take on a dream-like quality. His smile would match yours in brightness and happiness, and his heart would skip a beat. For once, he wouldn’t mind being called the cry-baby.
Germany: Oh boy would he be ever so serious before the ceremony began, never letting on that he was barely holding himself together, he was so nervous. The moment he sees you walking down the aisle, his heart would beat faster than ever, face heating up, and yes, tears welling in his eyes. For a moment he would forget his own nervousness, and be completely immersed in you, not daring to breathe. In just a few steps, a few words, the two of you would be announced as “Herr and Frau”, and that meant the world to him.
Japan: He’d succumb easily to the tears. Of course he’d try for a serious front but it wouldn’t get him very far. Yet he’d cry with pride, overjoyed that finally it was his turn to live something he had only ever dreamed about. He’d vow to himself then that he’d do everything he could and even more to give you all the love you deserved.
Romano: He wasn’t crying, you were! Well to be truthful, you both were crying. Everything he’d hoped for, recognition, love, and someone who cared for him, was really coming together. Before you, he had felt hopeless. But now, as he watched you walk down that aisle, he’d never be so happy that he had found you than in that moment.
Prussia: If you thought that Germany was nervous at his wedding, you have severely underestimated how much his brother could outdo him in this category. The poor fellow would be bouncing on the balls of his feet by the time you made your appearance. Once he sees you though, he’d freeze. A string of what one could only gather as a nervous string of babble would wheeze out of him from under his breath. The tears would only hit him halfway through the ceremony though.
