Yeah, sorry about that. I exported the pages as PNGs without compression and didn’t realize how massive they’d get until it was already published. This was actually my first time doing a full typeset on desktop, and before this, I was only working on through a mobile phone. I prioritized quality, but now I get how bloated the result turned out.
Just a short FYI; When you're exporting to PNGs you don't have to worry about image quality. Other than JPG PNG compression is lossless. Just set the compression rate to MAX. The images just take a bit longer to render depending on the power of your PC of course.
Got slightly confused by the title ... I would assume that the prequel would be "shokuba no senpai" without the 2, but that continuation of senpai and the sea does make me confused a little bit, since there actually seems to be an handuful of "special" chapters, including a sea chapter ... is there a chronological order to this series?
