SEE ALSO: Rain raises fans' curiosity as he teases upcoming announcement of some 'good news'

Rain recently posted on his Twitter for the first time since he entered mandatory military service almost three years ago "ready? today .... 11:59am" 

He also updated his profile image with his comeback image with the caption "30 SEXY RAIN". Rain will be releasing his 6th album on January 6th titled "Rain Effect" with two title songs '30 Sexy' and 'La Song'. 

'30 Sexy' will give off the variety of his free vocal talents as compared to 'La Song' which will be the type of song that Rain has never tried. 'La Song' will feature old school hip hop, electronic, rock, and punk all coming together. 

So are you ready for Rain?
