Woolim Entertainment has now revealed mysterious photos of INFINITE's Dongwoo and Woohyun.

Previously released photos featuring members�L,�Sungyeol, and�Sunggyu as well as a video teaser have left fans speculating if there's any connection between the releases.

The agency posted the following messages on the group's official Twitter:�"October 25, 2012, Thursday. Relatively warm weather today! Reveal of Dongwoo's photo! Have a good day, and look forward to tomorrow's photo~!" and�"October 26, 2012, Friday. The day that ends the week! Woohyun is the subject of today's photo! Look forward to tomorrow's photo as well."

What is intriguing about the photos is that each member is holding up a sign with a different syllable. So far,�L's says "Na", Sungyeol's says "Neung", Sunggyu's reads "Dae", Dongwoo "Se", and Woohyun "Yo". Hoya and Sungjong's photos have yet to be released, and fans are still guessing the complete message.
