Her name was Kassandra? That was an oddly human-like name. Or maybe it meant something else? He shouldn’t make baseless assumptions. Regardless, this meant that she could hear him and understand him to some degree. He could not help but be fascinated by her. What was she? The first thing that came to mind was a mermaid... but those were supposed to only be legends and fairy tales. 

He was glad to see her mood improve. Seeing her smile so brightly made him blush. But now was not the time to be flustered.

He pressed his mouth closer to the glass and said, “Hiro.” Then he pointed to himself to try to say that it was what he was called. To make sure she understood, he pointed to her and said, “Kassandra.” then pointed back to himself and said, “Hiro.” 

As he pulled back, he noticed that he left a fog on the glass. So he drew a smiley face and a very cartoonish fish.
