Dear Elder Wells,
I am Brother Hyun Seog Cho, who is Elder Cho's father. I heard from Sister Olson and President Jennings that you are one of the best missionaries. When I heard that you would be my son's trainer, I was very glad and happy.
As a father, I know that Elder Cho will need your many helps on almost everything he does as a new full-time missionary. However, I believe that you will be the best to help him to be improved as a successful missionary as you are.
In my personal and family prayers, praying for your success is included, please know. I love you as much as I do my son, because you are my son's Companion.
Hyun Seog Cho
