What does Jolin Tsai's MV of Prague Square mean? I don't understand it.

The story goes like this:

Prague is a beautiful city.

First, it describes the romantic scenery there.

A beautiful and kind nun looks at the square in the cathedral.

A strange beautiful boy is playing the piano and singing a wandering song.

Girls follow the song and watch him quietly.

Then they begin to fantasize about their love.

"Steal him.

But "the monk said no", because nuns can't be moved.

She had a dream for a while, "After waking up, there was nothing."

She began to make a wish in the wishing pool, praying for a beautiful love for herself.

"The picture of the pigeons with their backs to the sunset was too beautiful for me to watch"

In fact, It's because of that boy that the picture is so beautiful.

She went to an empty corridor and started dancing.

Listening to his singing and piano sound not far away.

She felt that her heart could not be separated from him.

"You really can't get used to it without me"

They met

In a cafe.

This is the final answer to the story.
