On the other hand, Seungmin wrote on his Instagram, saying that it been a long time since they released an "SKZ-RECORD" for STAY to sing. He continued that their cover is the song that he wanted to cover. Seungmin explained that he asked Han's help for the song since it has a rap part, but then he realized that it would be better for Han to be singing alongside him.

Furthermore, Seungmin thanked Chan for helping them record the song. "Because we had to try to pull off emotions of the original song, I believe that we were able to learn a lot through this 'SKZ-RECORD.' Please enjoy listening to our song this time as well, STAY."
