"This is annoying." Yoona facepalmed as she let herself sit down, "Aunt Soo In just told me, to 'make you mine before someone else claims you'." She said making air quotes.
Sehun just stood beside her trying his best to not laugh, his mother always said that you should keep up a 'decent' image at formal occasions, especially at weddings like these. He sighed at the end of his laughter, "You could've just asked Seunggi hyung to be your date." 

"You're kidding. If he was here, you'd be witnessing two weddings today, Na-ra unnie's, and mine considering how badly mother wants me to get married." Yoona said derp-faced.
"Now, this is annoying. You obviously don't object to that idea. You and hyung make a decent couple, telling your parents about him isn't a bad idea, he's a good guy, they'd like him." Sehun said rolling his eyes as he took a seat beside her.
"Oh please, we're way better than decent, but he should settle down first, get his career planned out. When mom and dad meet him officially, we will marry." She said resting her elbows on the table.
"So, I'll have to handle a year more of, 'You and Yoona would make the best couple', side-notes?" 
"Hey, it's not my fault everyone ends up thinking we're together, or we 'should' be together." She said in an in-my-defense way.
"Noona, you've got problems. Why can't you just go somewhere, without dragging me along as a date?" He said facing her.
"Firstly, because everyone in my family knows you and actually like you, you're a safe choice. Secondly, because mother thinks I'm a loner, so she's not a fan of me attending family functions alone." She paused for a second to smile at him, "And, thirdly, because it's comfortable with you, I've known you forever. If I were with someone else right now, I'd actually feel like I'm cheating on Seunggi."
He glared at her for a while. "Firstly, Everyone likes me. Secondly, you are a loner. And thirdly, how is it cheating, if he knows and actually approves of this?" He said widening his eyes urging on his sarcastic curiosity.
"My conscience." She said as she comfortably rested her head on his shoulder, with a tired yawn.
"Did you get any sleep yesterday?" He asked with concern
"I stayed up talking to him, lost track of time." 
"Figures." Sehun said with the why-am-I-not-surprised expression.
"How's university treating you though?" Yoona asked adjusting her head, his shoulders were really broad and yet surprisingly comforting.
"Glad you asked, great actually." He stated.
"Met anyone 'special' yet? She said smirking, finally raising her head.
"Would you like that? Aren't you supposed to 'make me yours, before someone else claims me'.? He joked returning the smirk.
"Way to dodge a question, and you wish."
