Written by Jo Yoon-kyung and composed by Kella Armitage, GG Ramirez, and Jurek, "Copycat" has been described as a nu-disco style K-pop song.

[1] On June 22, 2022, IST Entertainment announced that Apink Chobom would be releasing their debut single album Copycat on July 12.

[3] The music video for "Copycat" was directed by Wanda and featured choreography from Kiel Tutin and Yoon Mi-yeon.

Na also highlighted "Feel Something", writing that it "comes across as two separate tracks rather than an interconnected unit, while at the same time hinting at what makes this pair a duo and a subunit within a larger group".

[8] IZM's Jeong Da-yeol compared "Copycat" to Doja Cat and SZA's "Kiss Me More" and noted the hip-hop beat change in the second half of the song.
