The icy-haired boy stared at the girl for a minute, not saying anything. Finally, he grasped her hand gently and shook it. "...Thank you for helping him. I hope he didn't cause any trouble." He looked off to the side a bit awkwardly himself as a light blush covered his features. 

Kido bounced out from behind Moe happily to hug the other boy as he let go of her hand. "Don't worry, he's a bit shy sometimes, but he's really nice! Felice's my best friend, you know, so I'm glad that now you know him too!" 
As soon as he finished speaking, Felice attempted to push the cheerful boy off of him, but with little success. "Hey! You're gonna give her the wrong idea if you say things like that! And could you get off? We have to go, anyway." 
Kido eventually let go at the reminder, but turned to Moe once more before leaving. "Thanks again. I hope we see each other again soon! Oh, but Felice will be performing here again later tonight if you happen to come back this way--!" 

The boy was dragged away by his grumpier companion as he tried to mention this, but he managed to wave back at her as they left. "See you next time!"
