Through the ballroom

You've been involved in ballroom dancing since childhood, you've met a lot of competitors in this sport, you've become a professional and you've only won gold in competitions, but because of the training and overexertion, your body ached and you couldn't walk normally.
One day after the competition it was raining, you accidentally slipped on a puddle and fell into a deep ravine.
You were in a lot of pain, but you decided to continue home. People passed by, busy with their own affairs. You walked through the pain but fainted.
You woke up in the hospital with your right leg bandaged in plaster. You looked around, no one was there.

After you were discharged, you sat at home and your mother came to see you. You still hadn’t written to the trainer that you had broken your leg, you hadn’t told anyone, but it was bound to happen...

When you broke your leg, you had a competition coming up in a month. You felt guilty about betraying your partner and decided to go to training.

When you arrived, you saw your partner with another partner. You were surprised and angry. Then the coach came up to you and told you that you couldn't dance with a broken leg and that he had found a replacement for you. He told you to go home, but you stayed to watch the new partner. He was a beginner and didn't know much. You didn't like that your partner was dancing with someone else.
