歌詞

One day Mizuka explored her little home

And found a tiny window all alone

Curious, she peeked, and what did she see?

A little girl smiling back at me

Tap, tap, tap on the glass

The little girl taps back at last

We laughed, we played, peek-a-boo

A friend in the window, just us two

We played our games and had so much fun

Until another voice called out, "Come, my hun"

Mizuka turned, it was her mother near

"Time to eat, my dear" she heard so clear

Tap, tap, tap on the glass

The little girl taps back at last

We laughed, we played, peek-a-boo

A friend in the window, just us two

One day her mother softly said

"This window is a mirror instead

The girl you see, smiling back at you

Is yourself, shining through and through"

Tap, tap, tap on the glass

A friend forever, that will last

Every day, we play anew

The little window shows me you
