"Come in!" Jaebum said, stepping aside for Mark and giving him a friendly smile. Mark dipped his head a little and murmured a shy greeting, wandering into the living area where he found Jackson sitting cross legged at the coffee table, pouring over a book and several papers. The air smelled like cheese, the scent wafting from the kitchen and making Mark's stomach growl. He wondered if that was the lunch Jackson had promised him.
"Hey, Jackson," Mark said softly, and Jackson's head whipped up, his confused expression morphing immediately into a wide grin.
"Mark! Dude! I'm glad you came!"
Jackson got up and promptly handed Mark the notes he'd forgotten the day before; proud of himself. 
"They're all fine and organized," he added. Mark just stared at him. 
"You know I'm going to have to scatter them again if we're studying," he said, and Jackson's face fell, making Mark chuckle.
"I appreciate the sentiment, though," he mumbled, shaking his head and biting back his smile as he sat down.
"Fine, then, I'm gonna go get our lunch," Jackson huffed, pretending to be annoyed. Mark could hear him clattering about the kitchen and opening the small over door, taking out what he presumed was food.
"What did you make?" Mark asked when Jackson returned, trying to peek at the tray the other boy carried from his seat on the floor.
"Nachos," Jackson said, unceremoniously setting the still warm tray directly onto the wood coffee table.
Mark's mouth watered; they were only tortilla chips with melted cheese and chopped onions, but they smelled so enticing that his stomach growled loudly. He immediately put a hand over his abdomen, embarrassed when Jackson laughed at him. He would have made a biting remark, maybe something about Jackson's hyena laugh, but Jaebum and another boy Mark didn't recognize entered the room and sat down on the opposite side of the coffee table.
"I'm starving," Jaebum announced, shoving a handful of nachos into his mouth, devouring them with ease despite being so fresh out of the oven.
"Same," the new boy agreed, who Mark realized must be Jinyoung, Jackson and Jaebum's other roommate.
Mark reached out to take some as well, but realized Jinyoung was staring at him, head tilted, obviously giving him a look-over.
"Mark, right?" he said, raising his eyebrow. Mark nodded shyly.
"Ah, you are kinda cute!"
"Excuse me?" Mark coughed, nearly inhaling a chip.
"Jackson said--"
"Shut up!"
Mark saw a leg fly out under the table out of the corner of his eye, Jackson's heel making an unpleasant noise when it collided with Jinyoung's shin. Jinyoung gave Jackson a nasty glare, rubbing his probably bruised leg.
"The fuck was that for?" he asked Jackson, who merely stuck out his lower lip and sulked at Jinyoung.
"Are you Jinyoung?" Mark asked softly, trying to draw attention away from whatever was going on between him and Jackson. Jinyoung smiled, nodding.
"Yeah!" he replied, wrinkling his nose at Jackson and taking some more chips. "I didn't get to meet you yesterday, but I'm glad you could make it. Jackson was excited that someone else could share his misery when we tease him for his Korean pronunciation."
Mark blushed. Right, Jinyoung and Jaebum were native speakers. If they thought Jackson was bad, they'd outright laugh at his own terrible accent.
"I'm glad?" Mark said, his words sounding more like a question than anything. Jinyoung and Jaebum laughed, and so did Jackson. Mark eventually joined in, happy that Jackson and his roommates were so easy to get along with.
