It would be very satisfying to see her either get disowned(her attempted murder being known to all) or her family lose their wealth due some corruption cases or debt.
That way she losses her plot armor which is "wealth and connections" .
How fun would it be to see her gradually lose friends and have the people she screwed with in the past get revenge on her now that she has no protection.
Knowing some manga logic, she will probably won't lose and suffer that much and will most probably get some sort of redemption arc. We will probably even see sad flashbacks and some of the readers even sympathizing with her at that time.
In this kind of harem-ish setting it would be pretty shocking if she and her friends even get their due.
