Neptune: I don't get it. What's going on?

Author-san: I don't know, but the Japanese text says this:

Yesterday's live was a lot of fun ...
I love everyone at Morfonica ...!
But from the next day, everyone seems to be aloof ...?
Wow, I've done something ...!  ??

Kaito: I think the dialogue is from Mashiro.

(Y/N): Mashiro? What did she do?

Author-san: Honestly, I have no idea. So, we might find out this Thursday night.
