That's a song about never 
forgetting a girl you lost, isn't it?
Er handelt von einem Mädchen, das man 
verloren hat und niemals vergessen konnte, oder?
Es una canción sobre nunca olvidar 
a una chica que perdiste, ¿no?
Una canción sobre nunca olvidar 
a una chica que has perdido, ¿no?
É sobre o cara que nunca se
esqueceu da garota que perdeu, não?
