Broadcasted on December 1, KBS 2TV's 'Entertainment Weekly' welcomed Rain to the show where he revealed the main reason for titling his comeback song "Gang".

When asked if his "body has become slower/ gestures duller", the singer responded, "It's true.� Honestly, it's not that my body has become slower but full of pain.� I have chronic muscle pain, neck disc, and arthritis. That's why the title of my latest track is 'Gang' (a slang expression used to describe giving one's all.) I clenched my teeth in order to prepare for the comeback."
