Once there was a child living with his mother. His mother had only one eye. He hated her... she was such an embarrassment for him. His mom ran a small shop at a flea market. She collected little weeds and such to sell... anything for the money they needed.

One day during school. That was a field day, and his mom came to see him. He was so embarrassed.

How could she do this to me? He threw her a hateful look and ran out. The next day at school...all the children taunted him "Your mom only has one eye?!"

He wished that his mom would just disappear from this world so he said to his mom, "Mom, why don't you have the other eye?! You're only going to make me a laughingstock. Why don't you just die?" His mom did not respond. He felt a little bad, but at the same time, he thought that he had said what he wanted to say all this time. Maybe it was because his mom hadn't punished him, but he didn't think that he had hurt her feelings very badly.
That night...he woke up, and went to the kitchen to get a glass of water. His mom was crying there, so quietly, as if she was afraid that she might wake him. He took a look at her, and then turned away. Even so, he hated his mother who was crying out of her one eye. So he told himself that he would grow up and become successful, because he hated my one-eyed mom and our desperate poverty
Then he studied really hard. He left his mother and went to Seoul and studied, and got accepted in the Seoul University with all the confidence he had. Then, he got married. Had kids, bought his own house. Now he was living happily as a successful man. He liked it here because it was a place that doesn't remind his mom.

This happiness was getting bigger and bigger, when someone unexpected came to see him "What?! Who's this?!" ...It was his one eye mother. He felt as if the whole sky was falling apart on him. His little girl ran away, scared of his mom's eye.
And he screamed at her, "Who are you? I don't know you!!!" "How dare you come to my house and scare my daughter! GET OUT OF HERE! NOW!!!" And his mother quietly answered, "oh, I'm so sorry. I may have gotten the wrong address," and she disappeared.

One day, a letter regarding a school reunion came to his house. He lied to his wife saying that he was going on a business trip. After the reunion, he went his old house, just out of curiosity there, he found his mother fallen on the cold ground. But he did not shed a single tear. She had a piece of paper in her hand.... it was a letter to him.
She wrote:
My son...
I think my life has been long enough now. And... I won't visit Seoul anymore... but would it be too much to ask if I wanted you to come visit me once in a while? I miss you so much. And I was so glad when I heard you were coming for the reunion. But I decided not to go to the school.... For you... I'm sorry that I only have one eye, and I was an embarrassment for you. You see, when you were very little, you got into an accident, and lost your eye. As a mother, I couldn't stand watching you having to grow up with only one eye... so I gave you mine...I was so proud of my son that was seeing a whole new world for me, in my place, with that eye. I was never upset at you for anything you did. The couple times that you were angry with me. I thought to myself, 'it's because he loves me.' I miss the times when you were still young around me.
I miss you so much. I love you. You mean the world to me.

His world shattered!!!
Then he cried for the person who lived for me... MY MOTHER
