I promise to love you.

I promise to keep you in my heart.

I promise to never forget you,

Even when we are apart.

I told you this before.

I told you can't stay.

I told you it's not my choice.

I have to go away.

I can hear you crying.

I can hear you screaming my name.

I can hear you calling,

But I won't return today.

I'm sorry I can't come back.

I'm sorry that I left.

I'm sorry it was unexpected.

This was my ultimate test. 

I couldn't keep my promise.

I couldn't fight to keep my life.

I couldn't stay with you forever.

I know I promised I wouldn't die.
