Blessed crowd for forcing that handholding.
Luluca seems like the kind of person who wouldn't mind the crowd. She's so interested in people. Though I'm sure getting separated from An would worry her. That being said, it wouldn't surprise me if she hadn't even lost An, but she happened to spot An and Shunpei suddenly meeting and stopped right there, out of sight. Luluca of all characters would rather enjoy the show than get between them.
