there is a k-pop song i heard a while back and loved it but i dont remember the name of the song o band at all. all i really remember is it was placed in a white room with silver-ish decor, there were five guys in the band, and they were wearing jerseys of some sort.... also the song was about amor and there was rapping. OH and there was a guy wearing some crazy sunglasses. if im remembering im sorry.
