Translation

I'm glad that we met
I wanted to think it was genuine
Hiding behind the strong shadow,
Pretending not to notice and draing it way, maybe?
The small letters that occasionally came,
Would they stop increasing?
The nice time we spent together,
I'd like to go back to it if I can
Are you by someone else's side now?
You come out in my dreams

That I loved you and you loved me
Was the Key of life that you showed me
The past that can't break and the beautiful memories,
Line them up in your heart
I even loved those tears
I can't take it out in the back of my heart
I even loved those tears

That I loved you and you loved me
Put a spell on me one more time
The flaw gazes at your sleeping face
Yes, like this, go on
I even love those different smiles
I'll understand straight foward
I even love those different smiles
