At first Micchi doesn't say anything. Zack's used to that now, though, after all the attempts he's made to speak to him in person that have never gotten more than a few syllables in return. He knows better than to push. Micchi called for a reason; if Zack waits, he'll find his words.

"Something... good happened?" Micchi says at last, and Zack instantly understands the questioning tone in his voice; sometimes Zack still can't believe it when good things happen to him, either.

"Yeah?" Zack replies in a soft, encouraging tone. "That's good to hear, Micchi. You wanna talk about it?" He pauses a moment and then adds, "I can come meet you if it's something you'd rather talk about in person."
