Actress and former member of the 1st generation idol group, Fin.K.L, Sung Yuri will be reuniting with the microphone after 5 long years. Sung Yuri will be collaborating with singer Tim for the track, Lovers Declaration (?? ??). Both of their sweet and charming voices will mingle in this duet track, and serve as some major ear-candy. These two celebrities have been absent from the kpop scene for quite some time now, so their duet track will definitely be a treat for their long-awaited fans.
