A/N: Written for day six of ereri week on tumblr. AU, established relationship-ish. Sorry it's late; yesterday got away from me a little.

Green eyes flicked up to the door as it opened, temporarily letting in light from the noisy room outside, laminating the otherwise dark room. Eren sat closer to Levi's leg, nuzzling at his knee when he felt a hand casually reach down to scratch behind his ear. It was normally just the two of them here, except when Levi was making or collecting on a deal.

Eren loved it here. He didn't see outside the room often, let alone the building, but it was perfect. Since the first day Levi had found him, alone on the street, seriously considering doing away with his life, his existence had jumped from miserable to jubilant. There were many who'd say he was nothing more than a toy, a plaything to the older man, but Levi had more respect and love for him than he did anyone else. He hadn't needed to tell him; it was apparently every time he looked at him. Let them make judgments about why he chose to sit at the raven-haired man's feet like an obedient dog. He didn't have to explain himself to anybody.

Now, the older man then sat back against the soft cloth couch, frigid gaze surveying the newcomer. "Well?"

"Levi-san," the man said, fidgeting and visibly nervous since he'd entered.

"I don't have time for small talk. Do you have your payment or not?" Eren sat up a little straighter- it didn't look like it. "Down, boy," the voice lightly chided him. "At least let him answer." He didn't back down, but he didn't move further, emerald eyes fixed on the anxious visitor. "Well?" Levi asked again, tone almost bored.

"N-Not all of it, Sir."

"Not all of it?" was the calm inquiry, his companion now sitting up completely at his feet. "How much of it do you have?"

The man looked at his feet before answering, "I-I'm three thousand short."

There was a short tug at the nape of Eren's neck. Once released, he stood, walking up to the idiot. "As I've told you," Levi continued in dry monotone. "Eren can't talk, but as long as I've known him, he's never had a problem getting his point across."

Those bright orbs fixed on the nervous man, backing him against the wall, wide smile in place. "S-Sticking your plaything on me?" the visitor tried to sneer through racked nerves. "That's supposed to scare me?"

"You think I would ask him to hurt you?" Levi asked, a touch of true hurt to the tone. "Pain isn't really his thing; I wouldn't do that to him. You, however, may or may not appreciate what he has to offer."

It seemed to finally click for the other what the suggestive glint in those green eyes meant. "One week," he gaped, not able to look from them now. "One week, and I'll have all of it, I promise you, Sir."

"Hn, I don't know- that's what you said about today. What do you think, Eren? How much do you want to play with him?"

Those eyes iced over him again, their glee nearly childlike, reaching out to gently tuck a hand under his chin, but abruptly broke away, and spun on his heel away from the visitor, retaking his seat next to Levi's leg. He wasn't that cute.

"Unfortunate. I do love to watch you work. Looks like you have another week; I'd make the most of it, were I you."

There was no reply. The man just left.

Eren relaxed, resting his head against Levi's knee, wishing he could vocalize how contented the other's fingers in his hair made him, but settled for rubbing his head appreciatively against the digits.

"Such a good boy," the older man praised him. "You seem tired though; come lay up here with me."

He was tired. Levi read him so well he didn't need words. Gladly, he curled up on the couch, the other's thigh his pillow, those lean fingers back in his hair.

"Good boy," the soft tone came again, and soon nodded off, lulled by the man's touch.
