The Five Worlds

I try to stop Charles but I can't see him anymore. Brandon calls me from the back "Dude. Let's go. Just leave him a while and he will be back." I catch up to him, and he continues to say "We are going to look around the river ......" But all I am thinking about is Charles. We keep walking until the sun sets and just before the day light goes away we find a building made of steel.
“Emm… It seems tough” I say.
“So it must be an excellent shelter” Brandon says while he is walking to the door of the building.
I follow him, enter the door. But some kind of force closes the door.
A strange voice speaks “Welcome, my friend. We need to play a little game now. You just need to guess the riddle. You will die if you fail. Eh… I think so. The only way to escape is to guess in 60 seconds. HAHAHA!!!”

You think it hides itself in deep.
Its heart is protected enough.
Nobody has ever seen it.
But you decide to see it.
You have many ways to defeat its armor.
When you are hurting it, making it into pieces.
You are tearing…
After you look back at what you’ve done.
Dry tears on your face.
You found that it doesn’t have a heart.
