Well, someone better get in touch with that high school student that wrote that original letter to the Prez and tell them they need to update it and send it to Yoon, not Moon, and soon!
Also, I think adding in some more details like "I really enjoy the fall and love eating songpyeon at Chuseok" and "My favourite food in the world is now bosintang" would pull even more at his heartstrings. Then finish the letter with the "Daehan Minguk" chant followed by "Dokdo Forever."
That should do it. Maybe squeeze in something about how your relationship with your K gal is going real good. If you have a picture of the two of you in Hanbok he'll probably hire you as English as a Second Language Foreign Consultant. Don't forget us little people. Standing on shoulders and all that.
