On December 11, the girl group held a special Naver V Live broadcast in light of their comeback with the repackage album 'Merry & Happy'. During the airing, the girls talked about the recording process and Nayeon commented, "I spilled blood, sweat, and tears."
She continued, "This song was very high overall. We had to record multiple times. I had to repeatedly do it again, and also had to stop and continue multiple times. Honestly, I believed the pitch will be leveled down when we actually go into recording but it was still high."
Despite the hardships, Nayeon optimistically added, "Fighting!"
