The story should describe Ella's trip to the concert that was held in another country.
<h3>How should we continue the story?</h3>
When she arrived in another country, the first thing she did was look at the map of the city to identify where the stadium was where the concert was going to take place. She later went out and took a bus and when she got to the stadium she saw that there was a long line to get in.
Due to the above, she had to wait about 3 hours to enter the concert. Later, her favorite artist came out and she enjoyed the concert all night until dawn.
