It wasn't that the Bartons didn't want to tell Cierra.
However, ever since their aunt married into the Riley family in New York and returned to Los Angeles, their mother had some conflicts with her grandfather. As a result, they had less contact with the Chester family in the next few years. As such, he did not tell the elders of the Chester family about it in detail.
As for the Chester family, they naturally knew Cierra, who had been lost since she was a child, had returned.
A few months ago, when Cierra had returned to the country, the Barton family had donated 170 million dollars, and they had sent gifts to him.
However, at that time, Cierra hadn't officially returned home, and the Barton family hadn't received any relatives from her grandfather's side. So far, they hadn't seen her yet.
"I'll wait for you to stay in Los Angeles for a while. You'll know all the relatives. Don't worry."
