Ethan

Once your house was full of light energy, but now there is darkness... Only darkness and your schizophrenia.

A year ago, your best friend Ethan died in an accident, but you didn't believe he was dead, you shouted to everyone, "HE COULDN'T HAVE DIE!" You were very lucky that you weren't taken to a mental hospital and were prescribed sedatives.
Everything only got worse, you saw his ghost, Ethan himself, who is now gently hugging his shoulders, helping him cope with a panic attack.

• Shh... Honey, I'm here...
  A voice muttered in your head, a voice eerily familiar and dear.
  He looked at you with such a living gaze, how could he die?
  Alive... Of course he's alive!

• Don't be afraid, I won't leave you.

You sat on your bed, hugging the air, alone and broken by your illness.
