"I'm not entirely sure you've packed a week's worth of essentials for us into this one small suitcase that you take to work every day with you, Shinichi."
"Oh, relax." Shinichi fastens his seat belt as the plane begins to taxi for takeoff. "We can buy whatever we didn't pack when we get there."
"Spoken like someone who was born into money." Kaito leans back into his seat, closing his eyes briefly as the plane picks up speed, leaning slightly towards Shinichi when he rests a hand over on his knee. "How long have you been planning this?"
"Not very long. Two or three months at the most, I would say." It had been two or three months of constant worrying if Kaito would sniff out his secret plan while he wasn't paying attention or if nothing would work out when it was time to put it into action, but Kaito didn't have to know that. Besides, the look on Kaito's face when he had told him when they were going had been entirely worth every night he had snuck up for research while Kaito was asleep. "Why? You were the one who wanted to go to Hokkaido."
"I simply cannot decide if I want to love to, or hate you."
Reaching over the armrest to pull Shinichi closer, Kaito leans out into the aisle for a quick check before kissing him, Shinichi not resisting the quiet laugh that bubbles out of him as Kaito kisses him again, and again, and again, muttering breathlessly in between.
"Perhaps I have something that can help you make up your mind." Shinichi nudges Kaito back gently, tucking a few stray hairs back into place behind Kaito's ear where Shinichi had been running his hands through his hair previously.
"And what's that?"
Shinichi doesn't think he'll be forgetting the way Kaito goes still anytime soon when he lays out the old, crumpled receipts from months ago, Kaito's handwriting now smudged and fading in places from frequent handling. Linking their hands together, prompting Kaito to look up from the receipts to stare at him in an odd mixture of astonishment and affection, Shinichi presses a kiss to his cheek.
"Whatever answer you decide upon, I still love you."
