Even though we argued a little yesterday
Today, we laugh and hug, embrace each other
Alright. Let’s make a promise
You are my best friend

Even if your worry may seem trivial
Don’t hold it in
But share it with each other. Promise me one more time

Yoona
When you laugh, I’m happy too
Yuri 
When you’re sad, my eyes tear up.

(all)
There is only one of you in this world my friend
You’re my joy and my soul
I’ll continue to treasure our importance
I swear to God
I love you my friend

Jessica/Tiffany
I’ll be your strength

Sunny
If you find a good movie, a song,
Or a person(guy), make sure to let share it with each other
Let’s make a promise together

Seohyun
Let’s not be stingy and
Buy each other meals
Let’s make a promise with our finger

The word friendship may sound awkward, but I think that word was created
To describe us.

We make pretty nicknames for each other and play around
Sometimes, we share our cool clothes
You’re number one in my speed dial.
You’ll always be my best friend
Forever you’re my friend
You’re my only one, my friend
Forever you’re my friend
You’re my only one, my friend

Hey, aren’t you my friend?
