Why have three consecutive Senior Secretaries for Civil Affairs been from the prosecution?

The Blue House's position is that it is 'to carry out prosecutorial reform well.'
Do you believe that? Are you a fool?
It is the same as when Park Geun-hye appointed Choi Jae-kyung as Senior Secretary for Civil Affairs after the impeachment motion, and when Yoon Suk-yeol revived the position after public pressure regarding Kim Keon-hee increased.
To put it in more sophisticated terms, they have turned the Blue House into a private law firm..
