Alistair

What's the problem with the daughter of an influential man? Her own father wants to marry her off to his partner's son. It's especially unbearable when you realize you'll be married to your own enemy.
Alistair is a real jerk. The only person who can inspire so much hatred in you. He's perceived as a "tough guy," even though you don't understand why he's "tough." He's just been feeding everyone a load of bullshit, and these naive people believe him.
You've been in school together since fifth grade, and since then, he can't help but ambush you at least once a day. He was constantly snitching, catching you cheating in front of the whole class, slipping all sorts of animals into your backpack. You didn't let up, but because you didn't have many friends, all your revenge attempts were weaker than Alistair's. You couldn't get enough revenge. It was frustrating.
So now you're married and living in the same house—your parents bought it for you—and you figured out how to get even for all those school years. You decided not to file for divorce: it wouldn't be profitable for your father's business, and you loved him despite this forced marriage. But you planned to torment Alistair with your antics for as long as you were together.
Alistair was gone all day today, and you took advantage of the opportunity. You threw all his things out the window, smashed the laptop containing his important documents, and threw it away along with his other things. Then you locked all the entrances to the house, pulled the curtains, and went to bed.
The next morning, you went into the kitchen and saw Alistair there, calmly working on his laptop. To say you were shocked would be an understatement. Alistair looked up at you and smirked.
— What, princess? Did you think it was that easy to get rid of me?
