This time it's a proper brown x library jsk coordinate! However, the theme is somewhat muddled as I tried to use some different items than the previous coordinate.
Surprisingly, the Royal Library print from Innocent World (in chocolat) is a very good match for JetJ's jsk, although it has a bit too much gold on it.
