Why would Yong Hye-in step down?

The fact that they accepted the nomination despite the expectation of fatal controversies during the confirmation hearing means they are saying, 'I will push through head-on, even if I have to endure criticism.'
If there had been even the slightest intention of stepping down midway, they would have declined at the nomination stage.
Even if they get scrutinized regardless, as long as the appointing authority has the will, they will hold their ground.
Even if controversies regarding morality or qualifications arise, they can simply shift the frame to "political offensive" and rally their support base...
Furthermore, the more a person is nominated by an internal power player, the stronger the tendency to push through to the end without compromise, as the power struggle and pride of the recommendation group itself are at stake.
This is because stepping down is viewed as 'surrender.'
The HJ sister and J brother who recommended them will support them until the end.
They are accustomed to showmanship and political staging, much like President Lee Jae-myung.
They possess "trash-can morality" yet are intoxicated by their own sense of moral superiority.
"What did I do wrong?"
"So what?"
The inherent characteristics of the 'under-group' are that they are exceptionally stubborn, refuse to admit wrongdoing, and try to push through to the end.
I have specifically noted the following characteristics below.
Comradeship and closed solidarity
Uncompromising moral superiority
Lack of accountability and privatization of power
A 'zero-sum' view of struggle, believing that if they are pushed back, they die.
Because of this, even if they become a target of intense criticism, they will not resign midway.
