Being nervous herself about what might happen, Hayashi Sakura came here earlier than she expected. She wanted to confront Tomoya Emi regarding her Facebook post, and maybe then she could clear this up with a good old conversation- the traditional way of how you get yourself out of trouble.
It's not like she expects Emi to listen to any of her requests anyway, but Sakura is still willing to talk her way out of this. If that won't resolve the current issue of a possible leak to her identity, then she doesn't know what to do anymore.
Once Hayashi Sakura arrived at the school, thanks to Yamaguchi Alan's generous offer to drive her to school even though she refused it at first, Sakura came to school early.
Of course, she didn't forget to thank the young man for his generosity, which the latter answered with his usual "Not a problem," statement with a friendly smile plastered on his face.
