I Stole The Male Lead’s First Night

I want to see him dead, but zeronis this is just a bad, no, terrible idea, this won’t go well
My point? Even if they have plot armor, there are too many things to take into consideration and it could end very badly, my 4 main points in a nutshell
1: he committed treason
2: the other prince, and maybe even the emperor aren’t keen about the duke, most likely not allies
3: no allies because of the duke’s coldness and Ripley doesn’t have many friends
4: if prince Sharman does die or even if he leaves threatened but with his life, the royals won’t let it go even with a good reason because of previous points and also this is still treason and a threat to royals (at least in my point of view, I wouldn’t let it go if one of my vassals attacked my son)
The duke already committed treason and will probably commit more crimes, unless he can somehow overthrow the royals (he might wanna have a good reason for doing so since he could be portraited as a tyrant who slayed the previous royals) he is going to have to find quick support, a good army and a chance to get rid of the emperor and his sons, maybe even the princess unless Ripley tells him to keeping her alive.
My future points:
If plot armor fails, will they be reencarnated or will it end in tragedy?
If they are reencarnated, will they be themselves or someone else?
If themselves: will they remember each other? Will Ripley still have her previous reencarnation’s memories? If not, will the duke even like original Ripley? Will it be a battle over again to win over Ripley?
If not themselves: will it be in Ripley’s original world? That would be interesting, would it be the duke saving Ripley from her previous bullying?
Sorry for the long post I simply have this in my head
