Modern AU
Corrin grinned as he checked himself out in the mirror. The plastic plates, painted to appear metal, were perfect. Even the cape was the perfect length. Corrin wanted to go full costume, but the convention centre did not allow people to enter without shoes. Still, from the ankles up he practically was the main character of Water Sign 14.
"Big brother!" Elise burst through his bedroom door, wearing a black and pink skirt. She gasped when she saw Corrin and dashed forward. Elise bounced around Corrin, poking and prodding at small points of his costume. "Wow! This is so cool!" She cheered.
Corrin smiled and patted her head. "You look just like the princess."
Elise giggled and smiled up at Corrin.
"Err...Elise?" Flora called out from a room down the hall.
"Yeah, big sis?" Elise replied, running to the door frame and leaning out into the hall. Corrin chuckled at the nickname. Elise had been calling Flora 'Big Sister,' for well over half a year now. At first Flora resisted it, she and Corrin weren't even engaged! Elise still kept it up, eventually whittling down Flora until she simply accepted the name. That was only within the first week of her finding out about their relationship.
"I...er...can't seem to get this dress right..." Flora called back.
"Oh don't worry about it dear!" Camilla announced, opening her door and marching down the hall. She wasn't going to the convention, but she still wanted to dote over her 'New Little Sister.'
Camilla shut the door to Elise's room, where Flora was changing, leaving Corrin and Elise staring out the hallway. Corrin shrugged and marching back into his room, pocketing his keys and wallet.
"So, when is Big Sis gonna...actually become Big Sis?" Elise asked, plopping herself on Corrin's bed.
Corrin rolled his eyes. "You know, even if I did happen to have a ring on me, I wouldn't tell you."
"Why not!?" Elise pouted, punching a curled hand into the mattress.
"Because within seconds you'd have already texted Sakura, Effie, and everyone else in your phone. I wouldn't even be able to walk ten steps without Flora finding out." Corrin deadpanned, crossing his arms and leaning against the wall.
Elise bit her cheek yet remained silent. She couldn't deny it was true.
"Still, let's just say...hypothetically..." Corrin began, smirking when he saw Elise's face. "...I may have picked out a ring online, and was thinking it looked good...and maybe, if I did such a thing, you would help me decide sometime on the weekend?"
Elise gasped. "Really!?"
Corrin reached out and covered her mouth. "Elise. This. Is. A. Secret." He stared directly into her eyes, completely serious."If you tell anyone, I will disown myself this family and you'll never see me again."
Elise nodded vigorously behind his hand. "Good." Corrin breathed out slowly, still wary of his sister's big mouth.
A few moments passed in silence, Elise seemingly too scared to speak, until Flora swept into the room. Her hair was tied up in two small twin tails, with a headband arcing across her head. She wore a mid outfit, modelled directly from the game, complete with a hidden -prop- knife up her sleeve.
Corrin didn't exactly have a thing for maids, but in that moment, he felt something within him scream to kiss her.
"How do I look?"
"Awesome, Big Sis!"
Corrin remained silent, staring at her as a blush began to grow on his face.
"Cor..rin?" Flora asked, waving in front of his face.
"Ah!" Corrin jerked back to reality. "Y-you look like an heaven. I...er I mean an angel...I...uh...wow..."
Flora rolled her eyes and made her way to the door. "Remember, after this you owe me ice cream."
"Yes love."
