Princess is in another castle

I am writing to you my love,
To tell you what I know you want to hear
You have been here before
You have been through this
You will be back here again
Your nemesis will strike you this way
Again and you will overcome again
Because that is the cycle
That you could break
But it will mutate
And come back for you again
You will level up!
get through the next level too
Where you will find that what you need to find,
is out to find you too.
