Lilac Foxes (Corrin x Gunter)
Prompt: All royals react to F!Corrin x Gunter engagement

"… What." Leo asked flatly.

Leo and his siblings had visited Corrin on several occasions as they grew, and that was time enough for all of them to notice how Corrin occasionally had… odd tastes. But this was unexpected. Here they stood in the halls of Castle Krakenburg, listening to Corrin's big announcement.

"Gunter and I are getting married!" Corrin repeated, just as happy as the first time.

"Yay! I'm so happy for you, Corrin!" Elise ran over and hugged Corrin. "Ooh, ooh, can I be the maid of honor? Can I? Can I?!"

Corrin ruffled Elise's hair. "Hahaha! We'll see, Elise."

Xander was awkwardly rubbing the back of his neck, and noticed Camilla starting to sniffle. "Camilla, what's wrong?"

"It's just… I promised myself I wouldn't cry! Our little princess is getting married!" Camilla went over to join Elise in embracing their sister. "Oh Corrin, you're growing up so fast!"

Corrin gasped. "I'm, so, sorry! I didn't mean to make you cry, Camilla!"

"Oh don't worry about me darling, I'm just so happy for you!"

"Um… Well… congratulations… little pr… Corrin." Xander was not up for Corrin's pet name right now. "If I may, how did this come to be?"

"Hm?" Corrin turned back to Xander as her sisters let go. "Oh, well remember how Gunter and I play catch sometimes?"

"Yes…" Xander answered, apprehensively.

"Well, we used to have this deal where if one of us missed, they would have to do what the other said." explained the princess, as if it were the simplest thing in the world.

Xander winced. "And he missed, so you asked him to marry you? Is Gunter even okay with that? Corrin, there are just some things you can't ask of people."

Corrin shook her head. "Oh no, it's not like that Xander. In fact, I'm the one who missed."

"Uh-huh…" Xander was approaching a cold sweat.

"So he asked me if there were anybody in the camp I had feelings for, back when we were still at war." Corrin explained. "So we found out that we actually had feelings for each other! Can you believe it?"

"I'd rather not…" Xander said to himself.

"We decided to wait until after everything with Father and the war had started to settle before telling you. But we just couldn't wait any longer! We wanted you to be the first ones to know, so we could have your blessing."

"Well I for one can't wait to help with the preparations!" Camilla began to pinch Corrin's cheek. "You'll look so cute in your wittle dwess!"

"Ow."

"And I can still be the maid of honor, right?" Elise was checking in on her claim.

Xander breathed deeply and gave a hollow smile. "Well… I can see this means a lot to you, Little Princess. And it has been a month since the war ended, so I'm sure you've taken time to… grasp the situation… Very well. You have my blessing."

"Oh, thank you Xander!" Corrin immediately hugged Xander and ran off. "I'm going to find Kaze now, he's going to help me tell Hinoka and Sakura about this!"

"Hehehee! I'm gonna go tell Effie and Arthur!" Elise announced, running off. Now with only three left in the room, Camilla turned to Xander.

"Xander, are you really okay with this?"

The young king sighed. "Well, it's just… there's such a wide age gap between them. Corrin had even referred to Gunter as a father figure before. She begged me not to repeat that to our father." Xander paused. "… However, this is what our little princess wants, so who am I to deny her happiness?"

"Aww, you're such a caring brother!" Camilla teased. "Corrin always did like her silver foxes. Well, more of a lilac fox in Gunter's case." She then turned to her remaining brother. "What about you, Leo? You've been awfully quiet this whole time."

Leo began to blush. "Well… I was…" Sigh. "Since we're not in front of Elise, I'll tell you. My mind wandered and… I accidentally thought about Corrin and Gunter… together."

Camilla gasped. "Leo! That's… oh gods, I didn't even consider that! Corrin's innocence! My little sister is too young to get married!"

Camilla immediately bolted down the hall. "Corrin, wait! I don't want you to grow up yet!"

Xander sighed, and Leo hung his head. "I apologize, I didn't-"

"No, no. She would've made the connection sooner or later. Better she sort her feelings now."

"Very well. So, what shall we do now?"

"We've put our faith in our sister numerous times. One more time can't hurt." Xander said with a hint of a smile, this time a sincere one.

"No, I was asking what you and I shall do with our afternoon."

"Oh." Xander paused. "… A quick game of chess before my meeting?"

"Sure."

A/N:

Welcome to Lost in Drabbles All Alone. Unofficial title, "Jakob's Fates Drabble Theater".

I've recently become a mod on a Fates drabble blog on tumblr (FE14Drabbles) and this will be a collection of everything I've written for them. All the mods are named after Fates characters, and mine is Jakob, hence why he's in the unofficial name here.

The first few of these have already been written and posted on there. So I'll be systematically updating this to include them. But once I'm caught up, they will all be posted here (and AO3) a certain amount of time after being posted on the tumblr blog.

As part of the process of becoming a mod, I had to write three or four drabbles that were requested by the followers of said blog. This was the first, and I think it was a good start. Humor is my preferred subject to write, and the idea of everyone reacting to Corrin's marriage to Gunter seemed ripe for comedy. This takes place after Conquest, but they have not had Kana yet.

Enjoy your stay. I will likely update later tonight or tomorrow, unless something goes wrong.
