Finding a manga drawing guidebook page?

[theteri]

I saw a picture of a page(scan?) from a "how to draw" book on this site, I think, that detailed how to draw pain? Like, it was a manga art syle where the author had commentary about how pain can be drawn and detailed about curling away from the pain? I remember the poster talking about this would help with spanking art? Edit:it was just a part of a book that detailed other emotions and how to draw them. The information given in the whole series was very widespread and detailed.

I know that the series it was from had at least seven volumes and I think the page itself was from volume 5? I had downloaded all of the volumes in pdf form on my phone but I somehow deleted the entirety of my downloads. I have been scouring this site and Google looking for the series or the post. It was difficult to find at the time as well. This is my last resort and I would be so incredibly grateful if you happen to know/find it.

Thank you for your time. I can try to add more detail if necessary, but my memory is pretty vague about it.

Edit: I found the book series, it was just the "Sketching Manga Style" series.
