On March 19, Wanna One released their new album '0+1=1 (I Promise You)' with the title track "Boomerang". Upon hearing the new song, several fans accused Wanna One of plagiarizing SF9's debut track "Fanfare" which was released back on October 4, 2016. These fans are claiming that both songs have the same beat in the beginning.

안녕하세요. 2년차 그룹 SF9을 덕질하는 한 데뷔팬입니다.
저희는 데뷔곡인 '팡파레' 를 표절당했습니다.
급히 만드느라 엉망이지만 영상을 보시면 도입부가 워너원의 신곡 '부메랑'과 매우 흡사한 것을 보실 수 있습니다.
저희는 YMC에게 피드백을 요청하는 바입니다.
