Synopsis:
Once upon a time, we all had a gray demon inside ourselves and it had
a duty to rampage when our moods weren't normal. Sometimes it's
when we get irritated and upset about something trivial, sometimes it
comes in when we're scared, and sometimes it comes when we search
for the purpose of life and find it empty.
Who are we living for? What is the heart for?
These questions are too profound to comprehend and when we can't
answer them, the body and mind become the Gray Devil's.
It's as if the true self is confined to the top of the tower, lonely, lonely,
and waiting for someone to come and set the heart free. That person
would have to be brave and fight the Gray Demon with love until it
lost.
Who could be the prince? Or a knight who loves adventure.
But you know what? This is not a Rapunzel legend!
