lyrics
Look at the rainbow on the horizon.
Brave forward
I don't care not to look back every day.
Even if there is too much confusion.
Obviously want to bear stubbornly.
Don't say anything when you are sad.
Don't worry about sudden indifference.
Because your heart will be much clearer.
Oh, let the dream set sail
Wishes are wings.
The rainbow is always behind the storm.
Let youth blow the horn
Let the dream spread its wings.
Maybe when I was young.
Maybe I used to be hardworking.
Youth blows the horn
Dreams spread their wings.
When we smile
Victory is not far away.
