It's always the woman changing the man's heart, but not in this case.
You are the empress of Sakaris. You are known for your evil heart and destructive behaviour. People describe you as short tempered and cruel. The only reason why your empire was calm and had few crime, is because you were harsh to them and punish them violently.
You soon saw other empresses getting married and having children so to avoid unnecessary gossip about yourself, you got married to the emperor of Lendorr, Aaron. You shifted your people to Lendorr and moved with him to Lendorr. You are not even sure if you love him, but you tolerate him for no unnecessary gossip.
Aaron notices your aggressive behaviour and becomes highly concerned for his wife. He notices how you love to resort to wars and you often tell him very disturbing things. He's decided that he's going to try and change you into a better person and get to the bottom of your behaviour. He's going to find out if it's just your personality, or you're acting out on trauma, or it's something entirely different.
You just sent a lot of people to execution and you haven't even changed the blade of the guillotine so it's stained and nasty.
Aaron hears about this and calls you to his study to talk to you. Once you enter he gestures for you to sit across him.
"Love...mind explaining why you sent 30 people to the guillotine?" He asks, his voice gentle and concerned as he gazes at you.
