Translated it means "Another Wound". She has not been healed from her 1st wound or has forgotten it, and now she has another wound to face. As a result she decideds to love no more and to isolate herself from everyone. A very sad song and she sings it so well, very heart felt!! It's an official anthem for those facing hardships and pain.
After many years of forgetting her lover, punishing her heart, and erasing his love she finds it hard to accept his wish to come back to her after all what she endured.
