《Expectation Girl sday》的歌詞如下：
Girl's day, I hope everything will be fine.
There will be sunshine every day, you don't have to worry.
But you don't know what I'm thinking, I hope you can hear my heart.
Girl's day, we will always be together.
Even if the world is in ruins, we will still be together.
(Chorus)
Girl's day, I hope you will be happy.
I will always accompany you, no matter what happens.
(Verse 2)
The sun rises and sets every day, but our love will never fade.
We will always be together, even if we are far apart.

Girl's day, I hope you will be happy.
I will always accompany you, no matter what happens.

The world is changing, but our love will never change.
We will always be together, no matter what happens.

Girl's day, I hope everything will be fine.
You are my only one, and I will always love you.
