Finished, Zhi Rui could feel a small fire of rage blossoming on the couple and Izaya's gut. She stared at them intensely one at a time, with a smile on her face.
Izaya momentarily thought about taking his daughter and going away. But when Zhi Rui's eerie smile faced him, It dawned on his mind.
'She's stronger than me now.' A chill run down his spine.
He stayed and worked for his daughter but in case of any danger, he would immediately take his daughter away, even if it was from a place she liked. But he realized, he didn't have that option anymore.
Zhi Rui had no need for threats or hostages. She has pure brute strength now. His chest deflated with the thought of his fate being in her hands.
The couple didn't react much, they both were ready to die together if something too intolerable for them happened, so as long as Zhi Rui kept her word of giving what they wanted. They didn't mind.
