Tak Jung-Hwa's simple question was akin to pouring water into sizzling oil. Mr. Qin's rage erupted in an instant. "Why should I know?! Why should I know who the hell that—cough cough!" He was so angry that he choked on his saliva and ended up almost hacking his lungs out.
Sharp-eyed, Nurse Chen moved to pop open the uppermost button of his shirt and rubbed his chest to make him breathe easier. His voice contained a hint of warning as he glanced at Tak Jung-Hwa. "Please refrain from bringing up sensitive topics that can provoke him. It's not good for his health."
"Cough cough… I– What am I talking about again? Ah, that's right, I told you to put two spoonfuls of sugar into my tea, didn't I?!" He chided the nurse angrily, having forgotten that he was talking about his son a few seconds ago.
"Yes, yes," Nurse Chen answered him smoothly, it seemed like this was not the first time they've had this conversation. "I will do it. But you have drunk your tea today, how about tomorrow?"
In case you're confused, let me try to sort out the timeline. Remember that the police is still unsure as to when Qin Zhen is replaced by the imposter ^^
Six months ago (November): Qin Zhen came out to his father and asked for blessing > there's a huge sum of money withdrawal from his bank account
Five months ago (December): the bartender noticed the imposter's hands > the imposter saved Miss Zhao from CEO Li
Two months ago (March): the imposter visited and dumped the payment for the next five years
His time of death is around four months ago
I hope this will helps you ^^
