"Y/n," Felix called to his sister. "I have a request."

Y/n turned to Felix. "Sure, what's up?"

"Can you tell Dorothea to back off?" Felix asked.

"I'm gonna need more context... why?" She inquired.

Felix rolled his eyes. "She won't stop flirting with me... it's making me uncomfortable. Please make her stop."

Y/n nodded. "Will do."

"Thanks, Y/n." Felix smiled slightly, and headed to the Blue Lions classroom.

Y/n and Dorothea had been best friends since their first day at the academy. So much so, that Dorothea transferred to the Blue Lions just so they could be together more.

"Hey, D, I was instructed to tell you to, and I quote, 'back off' from Felix. He doesn't like your flirting." Y/n grimaced, awaiting her reaction.

"He sure is a tough nut to crack... But, I suppose I will." Dorothea smiled.

"Thanks... anyway, how are you?" Y/n and her friend began heading toward the classroom.

She sighed. "I'm okay. I have a date later!"

"Of course you do, is it a knight?" Y/n asked.

She nodded, biting her lip a little. "He is so dreamy, Y/n."

"I can tell. You'll have to give me all the details! Don't leave a single part out." Y/n laughed, heading into the class, and taking her seat beside Dorothea.

Y/n dipped her quill into the ink to prepare for the lesson. 

"Ow! What the hell?" Y/n exclaimed after receiving a hard elbow to bicep by Dorothea.

"Sylvain has been staring at you." Dorothea giggled.

Y/n's head whipped to glance across the classroom, and her e/c eyes were met with Sylvain's chocolate brown ones.

To set the scene, Y/n and Felix were the childhood friends of Dimitri, Sylvain, and Ingrid. Y/n was always closest with Sylvain, enjoying his company the most. Over the years, Y/n had slowly developed feelings for him, even though he was older than her by a few years.

She quickly turned away, blushing.

Dorothea gasped. "You totally have a thing for him! Oh, you two would have the most beautiful babies!"

"Dorothea!!" Y/n exclaimed.

"Sorryyy, I'm just teasing." At that moment, Professor Byleth walked in, and began her lecture.

~~~~~~~~

"And that concludes today's lesson, remember to be working hard so you can earn the seal you need for your next certification. Class dismissed." Byleth smiled.

"Hey! Where are you going?" Y/n called after the songstress, who was leaving her behind.

"I have to go, I'll see you later!" Dorothea called.

Y/n sighed, putting her bags into her book bag.

"Hey, Y/n..." Y/n turned to see Sylvain leaning flirtatiously over her desk, his face only a few inches away from hers.

"H-Hello, Sylvain. What's up?" Y/n's eyes flickered to his lips for a moment before returning to meet his eyes.

He smirked. "I saw that. Anyway, I wanted to know if you'd like to have tea with me. Like, right now."

Y/n's whole body felt as if it were on fire. "Y-Yeah, definitely."

"Perfect," he smiled. "Let's go, milady." He bowed, making her laugh.

~~~~~~~~

Y/n laughed at one of his jokes.

"Y/n, there was actually a reason I wanted to see you today..." Sylvain said.

"You know you can tell me anything, right? We've known each other our whole lives." Y/n smiled.

"Okay... I just don't want to mess things up between us. I really like you. More than any other girl I've met. I just... you're different than them. You're different. You're unmatched to them. Your beauty, your personality, everything, is just better by a landslide," Sylvain smiled. "That's all I wanted to say."

Y/n felt like crying. Of course, she wouldn't, but she probably could if she tried. "Sylvain..." She leaned across the table, connecting her lips to his. He quickly took control, their tongues fighting for dominance, his winning.

"What the fuck."

"F-Felix!" Y/n yelped, pulling away from Sylvain, and staring at her brother.

"Um... hi, Felix." Sylvain blushed.

"If you break her heart, I'll break your goddamn face, Sylvain. I swear." Felix's face had no expression on it.

"I won't break her heart." Sylvain said.

"You'd better not... because I'm not kidding. We may be friends, but she's my sister. Okay?" Felix said.

Y/n smiled. "Thank you, Felix."

Felix fought a smile, messing up his sister's hair. "Be careful." He shot one more glare at Sylvain, and went to the training grounds.

"Yeah, Sylvie, he's not kidding." Y/n turned to him.

"Sylvie?" He blushed.

She nodded. "It suits you."

"Since it's you, I'll make an exception."
