The video starts off with Yoo Seung Woo and Sandeul praising each other musically, then talking about what a great chance it was for them to work together. Brother Su followed by explaining the song, "The word 'Oppa' is a very common word but there were moments when certain people called me that and it sounded different and special to me. When someone hears 'Noona', it could get them excited or feel different. It's a song made by those emotions and feelings when you meet the right and special person."
