Seeing through the Flames (Killua x OC) (Kurapika x OC)

When Alluka Left Killua - One-Shot

Killua tapped his finger on top of the table with a stern expression. It was making the tea in his cup vibrate. Across from him sat a bored Arla.

"Killua." She called out to him with a very neutral expression. He twitched and came to a stop.

"Y-yeah." He gave her a nervous smile as he then sipped his tea again to cover up his irritation.

"What exactly are you annoyed about?"

'Ah, it came... Arla's curiosity.' He looked out the window, pretending to be very nonchalant. "Nothing." However, when he glanced Arla's expression, he froze even further. Her neutral expression had changed into one of displeasure.

"Is...that so...?" She placed her cup down. "Then I guess you don't mind if I just leave? After all, I have better things to do than trying to have fun with someone who isn't paying attention at all to the person who they invited to hang out with." Her tone was hard and he knew that he had essentially screwed up.

"That's..." He let out a small sigh. "I'm just mad that Alluka's with those brats. It feels like they took her away from me so abruptly. I don't like it - this feeling..."

Arla blinked and then let out a warm smile again. "In that case, please just tell me that in the first place, so that I won't go assuming that you just enjoy wasting my time for no reason at all."

Sweat trickled down his cheek. 'The person I like can be...scary.' He placed his cup down. "...Arla, you can be quite cruel sometimes, you know that?" Killua blankly told her.

She blinked in confusion, tilting her head to the side a little. "Really? I thought that I was quite...normal."

He shrugged, his smile transforming into a small smirk. "Maybe a little airheaded, but I guess you can be normal now."

"...Can...now..." Arla sighed a little. "I thought that I was improving a lot, ever since I traveled for my job..." She sipped her tea again with a troubled expression on her face.

He let out a small laugh, eating a bite of the chocolate cake that was in front of him.

"But you know, Killua..." Arla's gaze warmed, overwhelmingly affectionate - or at least, he hoped that it did. "Even if you feel that way, the reason you accepted her decision is because you knew that they were all trustworthy and good people...and because you care about your little sister's happiness the most. Isn't that right?"

He leaned against the back of his chair, looking up at the light blue sky. "Yeah... As long as she's safe and happy, I'll be happy..." His smile looked forlorn, carefree, and affectionate.

Arla giggled in her hand, making him look at her questioningly. "You truly are a good older brother. It makes me wish you were my older brother." From the back of her mind, she could almost imagine her actual older brother crying in a corner of the cafe and telling their mother about how mean she was being right now. 'But then again, he could also be holding onto me like a madman while glaring at Killua as if he was some kind of a wild animal... I apologize to you greatly, Killua, if that is the case.' She sipped her tea to hide her laughter. 'If only Ai was here to confirm it...'

Killua seemed displeased as he frowned to himself. He leaned against his arm and looked away from her. "I don't want to be your brother."

"Eh?" Arla's eyes widened. She placed her cup down gently. "Killua...?"

His eyes locked with hers. She could almost feel herself drowning in those blue pools, as if they had the ability to take her to a new dimension - a very beautiful blue world. His expression remained stern and serious. "I don't want to be your brother." His voice rang clearly in her ears.
