A fantasy world, a group of fantasy people.
After saying goodbye to you, I need to sleep for a thousand years, but one day in heaven and one year on earth.
You reincarnate once every three months and four times a year.
A thousand years is four thousand times.
I have a one in seven billion chance of finding you.
We only have a one in 100,000 chance of falling in love.
You have no soul and I'm afraid I won't find you.
Concept: helplessness towards reality and the impossibility of fantasy
