What song is Beibei singing?

According to the original plot, Beibei sang the theme song and the ending song "Constellation Code" (only friends know) in the miracle dance of the little fairy in Balala. The following are the lyrics of Constellation Code:

Only friends know.

Take good care of it forever

A set of passwords

Let us together

Jump out of the happy dance

As long as you have confidence.

Dreams will come true.

It's a little secret.

The magical twelve stars

They are scattered all over the world.

Waiting for our password to be determined.

Just believe
