From this album, SE7EN focuses and shows his vocal skill that has been hidden from his flash dance moves. He took all the chorus of every tracks in the album, and controlled his vocal tones to fit each tracks. 1st single of the album "라 라 라 (La La La)", which is written by his fellow YG family member, TEDDY, is a pop ballad recorded by SE7EN’s matured vocal and emotion. The song is about the story of a man is left behind waiting alone for his love to come back. Especially, Se7en changed his vocal tones from the beginning of the song to the end of the song, so that he can express mellow melody and song’s psychedelic atmosphere well. In addition, in the song “잘할게 (I’ll Be A Good Man)” whose lyrics were written by BIGMAMA’s LEE, YOUNG HYUN, he pulls up his vocal to the maximum and orchestra supports his powerful voice to give a stronger impression.
