It's Prince William's coronation, 2031-ish, Prince William and Catherine, were getting crowned King and Queen Consort and George was making his oath as crown Prince.

You had attended the late King Charles' funeral last year as George's girlfriend. you and George were betrothed to be married as soon as you both turned 19. It had been decided two months ago on George's 18th birthday.

So back on the plot... You and George were going to walk down the walkway/coronation aisle together. You wouldn't be crowned but George would.

So it's the day of the coronation. You're in a dress like Princess Catherine in 2022 coronation of King Charles. You have a beautiful pair of earrings George gifted you, a bracelet from your beloved mum, and a headpiece with the four flowers of the UK. It was beautiful. You were beautiful as you walked next to George. In an outfit like his father's in 2020. He was wearing a pin from you and that was it. Your engagement ring shone on the white shoulder length gloves you were wearing.

(You're both 18. This is taking place in November)
