My Brother and Fiancé Went Crazy After I Dedicated Myself to the National Secrets Project

On the day I got engaged, my brother brought back a girl my age and said she was the biological one. My brother accused me of taking up twenty years of her life. The fiancé said that was his wife. I was kicked out of the house in despair. My brother and his fiancé traveled around with their real daughter, and even gave her the villa they prepared for me. It wasn't until half a month later that they suddenly thought of my birthday and discovered that I had participated in the country's ten-year secret program. They can't see me anymore. But the two people who should have been happy regretted it.
