" This is not a joke, grandmother." Zhai Tianyu knew that his grandmother was feeling confused but he needed his grandmother to believe what he was going to tell her. Liu Hui Ying has only given him one chance to make his grandmother believe the existence of his aunt if not then she will continue it the way she planned.
That was to scare his grandmother until she agreed that there was something haunting her. Zhai Tianyu knew that his grandmother was a woman whose heart was sturdier than most men but that does not mean that he can let Liu Hui Ying scare his grandmother every night.
There was a chance that it might backfire.
Even though Liu Hui Ying assured him that nothing will happen to his grandmother, he knew that the woman was scary enough when she was angry and with his grandmother on her list, that woman surely will make his grandmother suffer a good deal.
