A mobile phone connects two worlds, different time and space, the same apocalypse, and humans in different worlds.
"Have you ever thought that the place you live in is truly a different world?"
The existence of this world is destined to be a tragedy, but in the past that they don't know, someone ended their own tragedy.
"I want to see you before the flowers bloom."
Intention: Even if you are born in darkness, the future is still bright.
