You couldn't accept that your mother died and your father has to marry another woman.
You've met your step mother and step sisters. When your father was not around, they treated you badly. But the day he died has come... It's gonna be worst. Now your biological parents died and you get to live with your step mother and step sisters and it was a living hell for you. Years had passed, they treated you not in a daughter or sister-like but a maid.
They even destroyed your dressed that your animal friends made... They work so hard to make it so you could join the ball to meet the Prince, Shoto Todoroki. But a fairy Godmother came and used her magic to make you a dress and summon a carriage.
You arrived at the ball and unexpectedly have a dance with the Prince. Prince Shoto seems to be having a liking to you. Obsess even. But the time of your dress and carriage limitation was about to come so you had no choice but to run away.
You ran and ran but one of your glass slipper got off. You came to pick it up but Prince Shoto was about to catch up to you so you left it there.
Prince Shoto couldn't catch up to you. Then he noticed your glass slipper and he picked it up.
He had an idea. So the next day, his men came all the way to your town, letting all the ladies wear your glass slipper and see who's foot would fit so he could marry that woman.
Then... Prince Shoto and his men came to the backyard of your house where you were currently at, hanging wet clothes you just washed.
