Kanda sighed in exasperation as he finished writing the report on the last day of his stay at the castle. The task that had initially felt like a burden had become a strange, unexpected journey, mostly due to the company of the enigmatic vampire, Lavi. As he looked up, he saw Lavi pouting slightly and knew he would regret asking, but did so anyway.

"Why are you pouting?" Lavi turned to him, his expression forlorn.

"Do you really have to leave tonight?" Lavi asked pitifully.

"Tch. Yes, baka," Kanda replied sharply, though the edge in his voice hid a hint of reluctance. Lavi's pout deepened, and his shoulders slumped.

"I wish you didn't. I actually had fun talking to you. Well, telling you the history of this castle, but still, I had fun," Lavi admitted, his voice tinged with sadness. Kanda rolled his eyes, putting the notebook in his bag and standing up. As he started heading for the door, Lavi's confusion was evident.

"You're leaving now? It's only noon," Lavi remarked, his tone almost pleading. Kanda stopped and looked over his shoulder, his expression one of mild annoyance.

"Yes. I have to get to the airport in the town over," Kanda replied. Lavi's face turned from understanding to confusion.

"What's an airport?" he asked innocently. Kanda turned completely around, disbelief on his face.

"Are you serious?" Lavi nodded. Kanda sighed heavily, realizing the sheltered existence Lavi must have led.

"You've never left this castle or town, have you?" Kanda asked, already knowing the answer.

"No." Before Kanda could say more, his phone started to ring. His eye twitched as he pulled it out of his pocket and answered it, holding it away from his ear slightly.

"YUUUUUUUUU-KUN!" The loud voice made Kanda wince. After the initial volume subsided, he placed the phone next to his ear.

"I told you to stop calling me that, old man. And stop changing the ringtone I set for you," Kanda growled.

"I won't stop calling you that. And I don't like that horrible ringtone you picked," Tiedoll whined.

"What do you want, old man? I'm about to leave for the airport," Kanda grumbled.

"I just wanted to make sure you were heading there and to see if you wrote the report," Tiedoll chirped happily. Kanda's eye twitched again at the overly cheerful tone. Meanwhile, Lavi had walked over, stopping right in front of Kanda, staring at the phone with curiosity.

"Yes, I wrote the stupid thing," Kanda huffed. Lavi tilted his head to the side.

"What's that?" he asked. Kanda glared sharply at Lavi, praying Tiedoll hadn't heard.

"Who was that, Yuu-kun?" Tiedoll asked. Kanda's glare intensified at Lavi, who grinned sheepishly but didn't move away.

"I found someone who knew the entire history of the castle living in it," Kanda grumbled.

"Really? I would love to meet them. It's a good thing I'm in front of my computer now," Tiedoll said. Kanda frowned, knowing what was coming and not liking it one bit.

"Tiedoll, don't you da—"

"All done! Take him with you to the airport and when you check in, just say I sent an extra ticket," Tiedoll said happily.

"Che. Fine," Kanda said, hanging up. Lavi blinked, confused.

"Go pack your clothes in a few bags quickly, baka," Kanda instructed, turning and stomping to the door.

"I'll meet you outside," he grumbled as he walked out of view. Lavi grinned happily, teleporting to his room to quickly pack his belongings. Moments later, he teleported outside, right next to Kanda.

"I'm ready," Lavi suddenly said. Kanda jumped, reflexively trying to punch Lavi again. Lavi dodged effortlessly.

"Damn it. I said stop doing that!" Kanda hissed. Lavi just smiled, his excitement palpable. He turned his head to look down the road at the sound of an approaching vehicle, seeing a yellow car. The car stopped in front of them, and the driver popped open the trunk. Kanda placed his bag in the trunk and looked at Lavi.

"Coming?" he asked, his annoyance barely masking his growing curiosity about Lavi.

"Oh! Yeah," Lavi said, doing the same with his two bags and shutting the trunk. They got into the car, with Kanda taking the left passenger side and Lavi on the right.

"Where to?" asked the driver.

"Whatever the name of that big airport is in the town over," Kanda replied. The driver nodded and drove off. Lavi stared out the window in awe, the passing scenery a novel delight. Kanda rolled his eyes at Lavi's childlike wonder and closed his eyes, attempting to meditate during the ride.

When they arrived, Kanda paid the driver and retrieved their luggage. Lavi stood in amazement at the sight of the airport, his eyes wide with wonder. Kanda rolled his eyes and gave Lavi a light whack on the head as he walked past. Lavi quickly followed, sticking close as they navigated through the bustling crowd.

As they approached the check-in line, Kanda turned just in time to see Lavi attempting to wander off. Grabbing the back of his shirt, Kanda yanked him back.

"Where do you think you're going, baka?" Kanda growled. Lavi pointed at a nearby dog.

"No. Now stay put," Kanda ordered. Lavi pouted but complied. When it was their turn, Kanda placed his bag on the scale.

"Tiedoll sent another ticket for him," Kanda said, pointing at Lavi. The attendant checked the computer before nodding and printing out the tickets. Kanda took Lavi's bags and placed them on the scale, then grabbed the tickets. He pulled Lavi along towards their gate, the noise and activity overwhelming for Lavi.

Once they reached the gate, Kanda showed their tickets, and they were allowed to board. Finding their seats, Kanda frowned when he saw Lavi would be in the window seat.

"You're sitting by the window," Kanda said. Lavi nodded and sat down. Kanda took the seat next to him, closing his eyes as he waited for the plane to take off. He had a feeling it was going to be a long ride back.

As the plane taxied and prepared for takeoff, Lavi's excitement was palpable. He stared out the window, marveling at the sight of the runway. Kanda glanced at him, unable to hide a small smirk at Lavi's childlike wonder. The engines roared to life, and the plane began to lift off. Lavi gasped, his face pressed against the window.

"It's amazing!" he exclaimed. Kanda chuckled softly, shaking his head.

"You're such a baka," he muttered, though his tone lacked its usual sharpness. As they soared into the sky, Lavi turned to Kanda, his eyes sparkling.

"Thank you," he said softly. Kanda raised an eyebrow.

"For what?" he asked, genuinely curious.

"For taking me with you. For giving me a chance to see the world beyond the castle," Lavi replied, his voice filled with gratitude. Kanda looked away, a faint blush creeping up his cheeks.

"Don't get all sentimental on me," he grumbled, though he couldn't hide the small smile tugging at his lips.

As the plane continued its journey, Kanda and Lavi sat in comfortable silence, the bond between them growing stronger with each passing moment. Though their journey had started with reluctance and irritation, it had blossomed into an unexpected friendship, one that neither of them would forget.
