INFINITE appears to be preparing for a comeback with 'Last Romeo.'

Although there have been rumors since last year that INFINITE will be making a comeback in the first half of 2014, the group has been stealthy about it.

The teaser video's for 'Last Romeo' have appeared on Korean television, but have said nothing about whether it is actually a comeback or some other event for the fans. The initial video didn't even INFINITE's name or logo, while the newer teaser does say the group's name. The latest teaser video also added the latest INFINITE infinity sign, which INFINITE changes for each album.

Korean fans have also spotted ads for 'Last Romeo' in subway stations, specifically in the youth-oriented neighborhood of Hongdae.

The group has been dropping hints for a comeback for some time, so fans are assuming that 'Last Romeo' is the name of their next album or title track. However, INFINITE has also been prolific with releasing photo books and various assorted fanservices, so the group may have some other surprise for the fans.

INFINITE's official website also revealed the teaser image, but said nothing other than 'INFINITE SEASON 2,' giving no hints as to what that means.

Another website, also has the same image.

In January, INFINITE's website had a poll on it called 'Color of Infinite,' where fans could pick which colors the seven INFINITE members would wear. There is a high likelihood that the INFINITE members will be wearing outfits that match the colors that won for any 'Last Romeo' promotions.

If that is the case, Sungjong will wear yellow, Sungkyu will wear red, Woohyun will wear blue, L will wear black, Hoya will wear purple, Dongwoo will wear green, and Sungyeol will wear pink.

Although there has been no date announced by Woollim Entertainment for INFINITE's comeback, it appears that INFINITE will release 'Last Romeo' within the next two weeks.
