"Your impulsive action may lead them to act on her, be careful on how you approach the situation...." Su Xuan was a lawyer and he could only caution him, he already notice their behaviour, they trusted in Bai Qing and it was just kind of an emotional feeling
Sneakily they placed two chips in her palms while crying out, nobody noticed their movement apart from Bai Qing who immediately hide them in her dress rolling it and covering them, her back was facing them, so they didn't see anything and the CCTV cameras couldn't capture that moment.
She dragged them closer and hugged them tightly, they must have gone through a tough trauma and since they hadn't cried, she became their safety harbour and let go.
"I promise to safeguard the two of you..." She vowed and whispered promising them.
