L'amour est proche mais invisible

Ten years ago, Su Ning's father accumulated a huge gambling debt. One drunken night, to repay the debt, he sold his biological daughter to human traffickers for a hefty sum. As his daughter was being taken away by the traffickers, Su Ning's mother, Bai Ying, rushed after them but was stopped by Su Ning's father. After breaking free from him, she embraced Su Ning, but only had time to put a bracelet on her.
