YanJun knew what his friend was trying to do so he asked, "Do you think if I knew I will spend a few days in the hospital, I would have gone upstairs?"
That was his regret speaking. if he had respected their efforts and gone downstairs to meet them, all that had happened would not have happened and he won't have had a reason to spend a few days in the hospital taking drugs or he would be in pain.
The fact that his phone was not with him and that he could not go to his company was enough punishment for him and the thought that he got back part of his memory and his life was about to experience a change he felt he was not ready for, was something too hard to accept too.
He sighed when the man on the other end remained silent when he asked him that question. "I will rest now," he told the man since he was waiting for the chance to hang up.
