I won't let you down(당신을 실망시키지 않을 거예요)

A : Mom, please send me to England.

     I really want to be a great soccer player like Ji-Sung Park.

B : My son. It's not that easy to be a famous player.

     First, you have to be born a good player.

 

A : You know, Ji Sung was not a great player from the start.

     I promise you I won't let you down.

B : Well, I think you're really ready.

     Okay, let's do it then.
