Is it possible to file for bankruptcy or rehabilitation regarding the Ok Joo-hyun building case?

I heard the interest rate is 20% per year.
Looking at people around me who are applying for rehabilitation,
the interest almost disappears and they end up paying back only the principal, and the government helps out to some extent so they can at least make a living.
However, if your income is high, everything except the legal minimum living expenses goes toward paying off the principal.
Since she is a celebrity, high income is possible, so it might be possible to pay it off faster than others, and it would be even better if there is income earned through cash, etc.
