Everytime I look into your eyes
I feel the warmth of your embrace
You're the only one that I trust
Promise me that you'll always stay
So take my hand and hold it tight
Through the good times and the bad
I'll be by your side forever
Promise me that you'll love me still
I'll be there for you
Through everything that life may bring
You know I'll stand by your side
Promise me that you'll love me still
どんな時にも 離さないで
どんな夢を追い ながらも
ただ一つ願いを 胸に抱きしめてる
So take my hand and hold it tight
Through the good times and the bad
I'll be by your side forever
Promise me that you'll love me still
I'll be there for you
Through everything that life may bring
You know I'll stand by your side
Promise me that you'll love me still
どんな時にも 離さないで
そう誓ってね 愛してる
ずっと ずっと 愛してる
永遠に 愛してる
I'll be there for you
Through everything that life may bring
You know I'll stand by your side
Promise me that you'll love me still
Promise me that you'll always stay
