"I don't understand why these symptoms appeared?"
"Because the switch on his oxygen mask was pulled off by someone, he suffocated to death..."
"That's impossible. I know how important a respirator is to an asthma patient, and I checked it repeatedly."
"It was after your check that the switch wasn't put back on! So it was your negligence that resulted in these irreversible severe consequences." Tang Shize's expression was grave. Despite wanting to protect his daughter, he couldn't find a way to save her from the situation.
"Dad, that's impossible. I would never do something so foolish. I would never." Tang Qingxue hurriedly denied it. She clearly remembered what she had done and had never been careless.
