Chapter Text
By the time the rebellion moved their base to the frozen wasteland known as Hoth, Han and Luke had been in a tentative relationship for a few months. They hadn't gotten around to discussing what they were to each other yet, but they spent nearly all of their time together and spent most nights in the same bed, too.
So it was only fair that Luke (who had no prior experience with romantic relationships at all, let alone with someone like Han) had assumed they were exclusive. Now, Luke wasn't oblivious to Han's... friendly nature, and he was definitely more than aware of the fact that Han was a very, very attractive man, but that didn't mean he had to be okay with Han and Leia openly flirting at every given opportunity, especially when they did it right in front of him.
At first he didn't mind so much, given that he and Han hadn't started their involvement until after the battle of Yavin, but the longer it went on the more it started to bother Luke. Han was his, and he was insanely proud of that, but maybe Han didn't feel the same way about Luke? Was he not good enough for the smuggler? Was their relationship casual and meaningless to Han? Luke didn't know, but until Han told him that, he wasn't going to put up with Han and Leia's constant flirting.
So the next time Luke came across the two of them standing unnecessarily close in one of the icy hallways, he wrapped one of his arms tightly around Han's waist and leaned as much of his weight into Han's side as he could, without knocking them both over.
Han responded simply by wrapping his own arm around Luke's shoulders, and pulled him in even closer, until they were as close as was physically possible. Leia stopped talking and her eyes widened slightly, a look of dawning realization crossing over her face.
"Oh," she exclaimed softly, "are you two..." she stopped, and nodded her head slightly as if unsure of what to call them.
"Yes," Luke replied, almost too fast, tightening his grip on Han's waist even more. Han snorted at Luke's display of possessiveness and patted Luke's hip with the hand he'd had wrapped around his shoulders.
"Yeah, me and the kid are... well, I don't want to offend your delicate sensibilities, your worshipfulness,” Han said mockingly.
Leia glared at Han, and then turned to Luke, “I don’t know why the Sith you would want to be with this scruffy-looking moon jockey, but, if you’re happy, then...” Leia trailed off, but she didn’t need to continue, her meaning was clear. She understood that Han was Luke’s, and she wouldn’t mess with that, and she was glad her two friends were happy.
With one last contemptuous look at Han, Leia left the two of them alone in the frozen corridor. Han looked down at Luke, an odd expression coming over his face as he tried to hide a fond smile. “What was that about, kid? You know I’m yours, the princess is just my friend, the same as she is yours,” he said.
Luke looked down at his feet, a sheepish smile on his face. “You’re really mine?” he asked quietly.
”Of course I am, why else would I spend every waking minute with you, why else would I do this, huh?” with that, Han let go of Luke’s hip and leaned down to kiss him soundly on the lips.
Luke kissed back with great enthusiasm, pushing the taller man back to lean against the wall, neither of them breaking contact until they had to stop to breathe.
”Oh,” Luke said, gasping still from the kiss.
”Never gonna doubt me again, are ya, farm boy?”
”Not unless you give me reason to,” Luke replied.
”Well, I can’t promise that, not when you’re so cute when you’re jealous...” said Han.
”I was not jealous!” protested Luke.
”Oh really?”
”I was just... claiming what was mine.”
”Oh? Well now it’s my turn to claim what’s mine,” smirked Han, shoving Luke against the wall and burying his hands in the boy’s soft blond hair before kissing him again.
