"Dear Felix,

You'll never read this letter.
But I need to put these words somewhere.

I can't live without you.
Those voices in your head took you away from me.
And I intend to get you back.

I'll meet you again.
Then we'll be together forever.
And nothing would be able to separate us.

Yes, that's what I'm going to do.
I really can die for you.

I love you, Felix,

Changbin. "
