I mean he could organise her death and send her out from the palace, make some noble adopt her and then marry her.....
But noooo let's give her an scar on face what is the worse type of scar in Historycal settings, plus some trauma and send her to be a laundry maid, who are basically the lowest and everybody step on them (6 years) .... .
In mean time instead of bring the woman whom he "love" and make her an empress, lets just marry some insane bitch who killed off her sister, consumate the marriage - he would consumate it, it was just pure luck that the woman who was choosen is FL - but "I regret it, I still love you so here became my empress* ewwwwwwww noooo wtf
What the fuck kind of thought process was that? I didn’t want you to fuck my dad so I decided to burn half your face, and condemn you to 6 years of misery of working the worst job in the palace and social ostracism? Was the scar on his hand supposed to make us feel sorry for his ass, despite him being a literal prince and having all the privilege in the world? What the fuck was the author thinking writing this kind of plot?
