Translation by Rika Takahashi aka Fuu
Nee naishoni shitene muneno okuni hikaru
Please, keep this a secret — shining deep in my heart
Hoosekiyori kagayakuwa himitsu no kimochi wo
Is a secret feeling that shines more than jewels
Daremo kizukanaiyou kokorono umi sodatsu
Growing in the sea of my heart without anyone knowing
Sekaide tada hitotsunano himitsu no kimochi ne
Is a secret feeling that is unique in this world
Mewo tojirutabi omoidasunowa
What I remembere each time my eyes close
Egaoto yasashii koe
Is a smile and a friendly voice
Kitto ienai demo wasurenai
I won’t be able to say, but I won’t forget
Munewo utsu kono kodou
The pulse that beats on my heart
Nee naishoni shitene kokorono atsui kaze
Please, keep this a secret — the warm winds of the heart
Anatanidake uchiakeru himitsu no kimochi wo
The secret feeling that I’m telling you and only you
Anatato issho otonae no michi
Along the road to adulthood, I have — with you —
Ippozutsu susundekita
Walked step after step
Dakara hanasuno darenimo naisho
That’s why I’m telling you something you can’t tell anyone else
Hajimeteno koidakara
Because this is my first love
Nee naishoni shitene muneno okuni hikaru
Please, keep this a secret — shining deep in my heart
Sekaide hitotsu dakenano himitsu no kimochi wo
Is a secret feeling that is unique in this world
Himitsu no kimochi wo
Is a secret feeling
