The next fifteen minutes were spent watching the demonstration, which for Marinette, translated to watching everything Adrien did intently with a dreamy sort of smile on her face. Anyone who tried getting her attention would probably find it difficult to do so.

By the time it was over, her mood had improved, if that was even possible. She'd been content before, but now she was giddy and anxious and oh goodness he was coming over after all...

"Adrien! Hi!" That wasn't so bad. Maybe she could do this. "You were great. In the demonstration. Yea!"

Nailed it.
