>>52903569I'm really rusty due to not studying lately at all plus I'm probably N5 or something like that so there's stuff I dont know or might've understood wrong, but the gist of the text in the background is just Suityan hardcore gushing over Rika, something like "aaaaaaaaaaaa!! I love this woman!! She's my type!! Chili-chan Chili-chan Chili-chan kawaii!!" with a thousand more "Chili-chan"s and more gushing.
Thinking it might be quoting her actual gushing over Rika on-stream since this is really familiar, including some phrases I couldn't quite translate but got enough to remember. Oh, and Rika is just saying "what's wrong? Please take your seat."
