"Fun? And exercise?" He echoed. He knew what each were, even if he didn't practice either, but he didn't know how they could have fun around the barn. And he was sure they did enough exercising lifting and doing all that labor. But, Aoba didn't complain. He was staring to just assume 'Kuro knew best'. If he wanted to, then if Aoba had the strength then sure, he would follow. When his wings spread Aoba watched with childlike curiosity. He started to reach out to touch them, but pulled his hands behind his back. He didn't want to accidentally upset Kuro, or worse, freak him out. Then again, he didn't want to accidentally mess them up. Kuro did say they were fragile. 

The fallen angel took all that into consideration and decides to just watch. He looked over to Dani and smiled toward his silly behavior. "I hope he doesn't get upset if one of the animals succeeds..." His head turned when Kuro spoke in a soft manner. At the permission, Aoba lit up like a child and clasped his hands together. "Really? Can I?" He was answered when Kuro's wings spread out wider and he rocked a little on his toes. The fallen angel didn't know why his wings were so interesting to him, but he really wanted to examine them. And when he realized how excited he must've sounded, Aoba's face flushed lightly and he stood still. 

"Uhm, s-." He stopped and bit his tongue lightly before he could apologize. Instead, he nodded and slowly reached forward. His fingertips brushed against the thin wings and he smiled moving a little closer to brush his hand across. They were smooth and rather nice. Obviously they were much different from his sturdy and fluffy wings. It was still a nice feeling nonetheless. His hand went up, and he paused noticing the little hook on his wing. "Oh, you have a claw there." He gently poked at it, noting how sharp it was. He moved to the other wing and did the same thing. Curiously, he opened up his own wings fully. They weren't the same size. Kuro's wings were a little larger and wider than his. 

With a content nod, he looked up at Kuro. "Okay. What were you going to say about fun, and exercise?" He thought about flying, but he realized he didn't do much of it when he was in heaven. Not besides, shorts bursts of flight for speed. The idea didn't sound so bad, and for some reason it did intrigue him. But he wasn't going to fly- not until Kuro did at least.
