English translation:

It's so odd, I loved you so much for sure
I adapted myself entirely to you, I wanted to live for you
But as I kept doing so, I became unable to bear the storm inside my heart
I got to fully reveal my true self under the smiling mask

I'm the one I should love in this world
The shining me, the precious soul of mine
I realize only now, so I love me
Even if it's a little lacking, it's so beautiful

I'm the one I should love
(Even if I'm shaking and afraid, I walk on forward)
(I meet the real you, whom I had hidden inside the hurricane)

Why did I, like this,
Want to hide away my precious self
What was I so afraid of
That I had to hide my true self

I'm the one I should love in this world
My shining self, my precious soul
I finally realise it So I love me
Though I'm not perfect, I'm so beautiful
I'm the one I should love

I might be a little bit blunt and inadequate
You might not be able to see such things as a shy sparkle
But the fact that this version of me is my real self
My arms and legs, heart and soul that I have lived with until now

I want to love them in this world
The shining me, the precious soul of mine
I realize only now, so I love me
Though I'm not perfect, I'm so beautiful

I'm the one I should love
I'm the one I should love
I'm the one I should love
