Kim Woo Bin went to find his mother Choi Ji Na.

On the last episode of SBS Wednesday/Thursday drama "Heirs" Choi Young Do went to the restaurant where his mother (played by Choi Ji Na) was a representative.

On this day, Choi Young Do saw his mother working and just stood in front of the door and couldn't go in.

Afterwards, Young Do who went back to the store got courage to go back to the restaurant and Young Do's mom who saw him recognized him at once.

Young Do carefully said, "Hello" and as his mother asked if he was well, he said, "No."

Young Do's mom brushed his cheek saying, "You grew this much. My son, you're so handsome" and cried. She also said, "I'm so sorry. I'm so sorry that I couldn't wait for a while. I wanted to go see you soon but I'm sorry I didn't" as she hugged him.
