Do You Want to Know More About the Bloodline Suppression of Top Sister?

Is There That Kind of Bloodline Suppression from the Elder Sister, and the Younger Brother Suddenly Behaves?

I want to read a book similar to "After participating in a variety show with the black and red brother, the whole network became popular". My younger brother is usually very pushy and difficult to obey, and my older sister is as timid as a quail. I really like this kind of thing lately, please! ! ! ! !
