I can't translate this well enough to actually write a useful note, but if someone out there is more knowledgeable about it, then please do.
The first line, all the way up to に, seems to say "Next year, I'm also eating Kushikatsu." So, while doing that?
The second line just refers to the Dream of the Red Chamber, some Chinese epic. A really epic epic. I wanna read it now.
In any case, one of these lines is completely unrelated to the other, unless they eat that in the book. I really don't get it.
*nom nom*Next year, I'm also eating kushikatsu while going to the Kouroumu*.
Touhou Kouroumu (東方紅楼夢) is an annual Touhou series doujin event held at Shin-Osaka Seni City.
