I'm doing by Order

"No matter what Manager Jung says in his confession, I hope you will still be Su Yu, My son."

  What does the confession do with it?  What might Manager Jung be able to change the relationship between the mother and son?

  "I don't know. Do I still deserve to be your son? Am I still worthy or do you still deserve to be?"

  All these problems seem like a clump of tangled threads.  By obtaining valuable information from Manager Jung, Su Yu had discovered that his mother was at one end of this tangled thread.

  If Su Yu had pulled the thread out in a proper knot groove, he would probably have unraveled this entire lump and found the other end.  Either what or who, Su Yu would know once all these tangles were cleared up.

  "Do you know how much of a thing you have done?"

  There was great demand and pressure in Su Yu's words that Madam Su became mentally down.

  "I'm sorry, Yu."  Madan Su tried to hold back her tears.
