Son was able to reach where he is now bc of his father. He got personal training from his father every single day.
What Son's father says in the beginning:
"You cant achieve anything without effort. I want to sleep more as well, but you need to know that there's no future for you if you dont invest in yourself now."
Apparently, during that time, Son slacked off a little bit when his father wasnt around.
Son cant complain bc his father does the training all along with him from the beginning.
First time I've seen Son not smiling!
