After the brothers left, Yun Lui's parents decided to open the letters. One was from their son and the other was from Chi Yang, the Patriarch of the home where their son is staying currently.
They chose to read their son's letter first. Papa Yun moved closer to his wife and opened the letter wide in a way that she too could see the contents before both of them began reading it silently.
The Letter Reads:
Hello Mom and Dad,
It's your son, Yun Lui. I am very sorry that I have caused you both to worry about me all this time.
I do not have my past memories and so I cannot remember the reason for me leaving home. I am very sorry that I left at all in the first place.
