Before her brother Alex died from rescuing her, he made her promise. "Hua'er, p-promise me, t-hat no matter what y-you should live... live a happy and normal life. E-even if I no longer by your side I want to see your happy smile and hear your carefree laugh again...j-just like when you are still six...so keep on becoming more strong so no one is gonna hurt you again...a-and even if I'm no longer by your side...d-do not forget me my forever queen-"
"N-no.No.No.N-no! Please Alex please, don't just go like this please! You promise right? You promise that you will stay...always stay. Why leave me now? Alex wake up please wake up! I beg you..."but no matter how much she beg and cry the bloody man in her embrace is no longer breathing.
She seek revenge. Killed every member of their organization and so their leader. But she still died. Not from seeking revenge but from an accident. A plane crash incident that she boarded. But the heaven still have mercy on her. She was given a new life. And she will use this chance to fulfill her promise to Alex.
