The girls of 9-tie hit the streets to spread the word about their idol group. When the going gets tough, however, the tough get going!
♬ This is the tiny promise
we made to one another ♬
Esta es la pequeña promesa
Que nos hicimos el uno al otro
Jamais je n’ai de cesse
De tenir la promesse
Essa é a minúscula promessa
Que fizemos um ao outro
