No luck in finding a match, but I know who designed the identity:
http://www.wideandnarrow.co.th/

Wasn't able to spot a match either, probably a customization of an existing typeface.
Some client for customization: Seconda Round, Soft and XtraSoft, Accent Graphic, Minerva, Carisma, Euro Sans, Bodoni Sans, Seaside (probably the closest), Contax Sans

thanks so much for the helpful suggestions Ryuk!

I’m intrigued by the sample’s demi-serifs, but didn’t find anything similar with the requisite stroke contrast and serifs....

You're right Kevin that's probably why I assumed from the beginning it could have been started from a Sans (and not a Serif). 'Virgin Daisies' and 'Wide & Narrow' are from Thailand, maybe the customization was based on the latin counter-part of some font for the Thai language...
