“Be good, let me kiss you, just once.”
“Be good, you must listen to me. I’ll pamper you.”
“Be good, stay away from him. I don’t like it.”
......

“Be good and stop throwing a tantrum. Divorce doesn’t exist in my dictionary, only... a deceased spouse does.”

Hence, he insisted on replacing Mu Nianqing to give Luo Zheng a chance.

Chu Ci was only stating the worst case scenario… In reality, there wouldn't be any danger as long as she could stay calm.
