All three of us were stunned when the test results revealed that none of us were our mother’s biological sons. A secret buried for thirty years was finally brought to light.

Ever since we were young, the three of us had known that we didn’t have a father. Our mother raised us alone, working tirelessly to support us. She was an ordinary woman, not well-educated, doing manual labor just to get by. Throughout our school years, money was always tight. Many times, when tuition was overdue and classmates mocked us, I even got into fights. But whenever I saw my mother bow her head to teachers, apologizing and begging them not to expel me, my heart would ache with guilt. She was so gentle, so self-sacrificing, and yet I had caused her so much worry.

Despite everything, the three of us grew up and became successful. Each of us built a career, earned a living, and took turns caring for our mother. In her old age, she lived peacefully, surrounded by our love.

Then came the sudden blow.

Our mother was diagnosed with leukemia.

The three of us dropped everything and rushed back home. We consulted doctors, searched for treatment options, and finally decided that all three of us would undergo bone marrow testing to see if we could save her.

But when the results came back, the doctor looked at us with a strange expression and said quietly,
“None of you are biologically related to her.”

We were stunned.

How could that be? If she wasn’t our biological mother… then who were we?

With heavy hearts, we went to her bedside. As the eldest, I gathered the courage to ask the question that had been tormenting us. She looked at us in shock, as if she had never expected this secret to be revealed.

Then she told us the truth she had carried for over thirty years.

Our biological father had been a heartless man who betrayed his wife and disappeared. Our biological mother, gravely ill and with nowhere to turn, had entrusted her three children to this woman — the one we had always called “Mom.” She took us in, raised us as her own, and never once told us the truth.

Listening to her story, our hearts shattered.

The woman who raised us was not bound to us by blood, yet she had given us everything she had. She had sacrificed her youth, her health, and her entire life so that we could grow up safe, educated, and loved.

But fate was cruel.

None of us were a suitable bone marrow match.

As her condition worsened, our hearts broke even more. The woman who was not our biological mother had given us everything, while our biological parents had given us nothing but pain.

She was not the one who gave birth to us — but she was the one who truly gave us life.

And more than anyone else in this world, she deserved peace, love, and a healthy old age.
