"What the fuck are doing," Levi demanded as soon as he spotted them, stopping in front of their table with a tray of food in his hand.
Eren blinked, pulling up off of the straw in his mouth. "Eating?"
"I would've thought that was obvious, Levi." Erwin added, raising an eyebrow as he placed a French fry in his mouth.
"Not that," the shorter male ground out, setting his tray down with a sharp clack! "Why are you sharing a drink?"
There was a long pause as they stared at him before slowly comprehension dawned. Sharing a knowing glance before turning to Levi with a slow smirk, Erwin asked: "Is that it?"
"We literally kiss all the time, Levi." Eren added. "What's wrong with sharing a straw?"
"It's different," he insisted, settling into his own chair with a startling elegance. With his legs crossed and his droll stare he looked like he belonged on a throne.
"Of course it is," Erwin agreed, before promptly pulling the straw that had just been in Eren's mouth to his own.
Levi's scowl deepened. "Fucking gross."
"You're so weird," Eren grinned, chin in his hand as he watched his lover with fond exasperation. "I'm going to remember this the next time we have sex."
Erwin chuckled. "He's just going to insist that it's different."
"It is," Levi huffed, unraveling the paper wound around his sandwich with a quick twist.
"Like I said," Eren said, taking another drink much to the shorter male's disgust. "Weird."
