Joseph released his first double single ‘How Can I Forget You’.

The album includes the song of the same name and 'I Don't Want You to Be Happy' featuring Taeb2.

Like the sentence “You became a memory, and I remained in it,” the album deals with the person who became a memory and the person left behind in that memory.

'How Can I Forget You' was written by Joseph, composed and arranged with Guard, and played guitar by Geum Sang-heon.
