Park Jin-young
As opposed to their previous songs, the tracks on the mini-album were not written by Park Jin-young, but by Big Hit Entertainment founder and Park's long-time songwriting partner Bang Si-hyuk, who is famous for composing Baek Ji-young's "총 맞은 것처럼" ("Like Being Hit By a Bullet") and 8Eight's "심장이 없어" ("Without a Heart").
