From what I found, it's a novel (by the same name) written by Nathakorn

No. Sorry to say I don't. I got the info from a google search. Apparently, you can find the novel through official Thai e-book and digital publishing platforms. Because this specific novel has been adapted into a major live-action television adaptation titled Lust: The Series (produced by M Flow Entertainment and iQIYI), its digital availability is organized across major online web novel hubs.

MFlow isn’t involved – it’s MeMind Y x iQIYI – so Google’s AI is mistaken.

I looked and couldn’t find any novel titled “Lust” written by Nathakorn so not sure what your source is for that. It’a not a MAME novel either, though I wouldn’t be surprised if she’s the screenwriter. In any case, it’s looking more and more likely that this is an original script.
