He didn't know back then, but he certainly knows now.
He now understands just how difficult it had been for his mother, and recognizes that indeed it was all because of his own faults.
Given that understanding, he certainly also knows what changes he ought to make going forward, and how he should strive to correct it all.
At this moment, Liu Zheng had returned to the clinic.
After seeing a few patients, he was ready to take a good rest.
However, just as he was lying on the bed, preparing to rest for a bit, a sudden knock resounded at the door.
Not only that, the knocking was very intense, as if some serious incident had occurred.
This indeed made him very surprised; he had no idea what could have possibly happened all of a sudden.
So, he immediately got up from the bed, opened the door, and prepared to see who it was.
To his surprise, when he opened the door, he found Liu Jiaxin, her hair curled into big waves and wearing a red dress, standing before him.
