As many of you know, Key and Hanhae previously worked together as cast members on tvN's 'Amazing Saturday', up until Hanhae's mandatory military enlistment just yesterday (February 7).
Key's upcoming 'SM Station 3' release is titled "Cold" feat. Hanhae, a medium tempo R&B genre combining a soft electric piano with a vintage mood. Key participated in writing the lyrics for "Cold", illustrating the hurtful feelings of a man struggling through a breakup in the cold winter.
