In the end they all bow to her and apologize and she forgive them cus she doesn't blame them cus they were brainwashed
From what I read in the spoiler she is the replacement, but here the spoiler page of you wanna read them https://www.novelupdatesforum.com/threads/the-villainous-mastermind-gets-lucky-in-his-later-years-%ED%9D%91%EB%A7%89%EC%9D%98-%EB%A7%90%EB%85%84%EC%9A%B4%EC%9D%B4-%EC%A2%8B%EB%8B%A4.143683/
