The man from that family was unable to have children due to an injury, leaving them with only a sickly daughter. They didn't want their daughter to be bullied when she married into another family, nor did they want their lineage to end. They thought of raising a child at home early on so that after their passing, there would still be someone to take care of their daughter.
At that time, no matter how much I pleaded, Grandma wouldn't relent.
Just as I was about to be taken away by that couple, my cousin and her husband came back for a visit, stopped them, and talked privately with Grandma for a long time. Only then did Grandma relent, and I wasn't taken away by that couple.
Later on, it was my cousin who felt sorry for me and feared that after they left, Grandma would send me away to be a child bridegroom, so she begged her parents to take me with them.
My cousin and her husband initially disagreed, but they couldn't resist my cousin's persistence, so they eventually agreed.
