HyunA and DAWN will perform their first duet with 'PING PONG'.
On the afternoon of the 31st, the tracklist images were opened sequentially following the teaser announcing that the title song of Hyuna & Dawn's EP [1+1=1] is 'PING PONG' through P NATION's official SNS on the afternoon of the 31st.
First, the teaser video released with the phrase 'Play that PING PONG' is composed of sound and game console graphics. On the screen in the game console, the phrases 'HyunA DAWN', '1+1=1 PING PONG', and '2021.09.09 6PM KST' appear in sequence and attract attention.
According to the track list released next, Hyuna & Dawn's EP contains a total of 4 songs including the title song 'PING PONG', 'Deep Dive', 'XOXO', and 'We loved to death (I know)'. The track image, which consists of 4 cards containing the song name and atmosphere of each track, also has a kitsch atmosphere.
In particular, in this EP, Dawn was included in the lyrics and composition credits of all songs, and Hyuna also participated in writing and composing the lyrics for 'PING PONG' and 'XOXO' and writing the lyrics for 'We definitely loved to death (I know)'. 
In addition to the two of them, hit makers Yoo Gun-hyung, Kwon Philip, Kang Pil-seong, and SPACE ONE doubled the perfection of [1+1=1] by participating in composing and arranging.
