A time travel, heartbreaking
She fell to the bottom of the world and was bullied by others
This city that has forgotten kindness has collapsed her world
From then on, she determined to become stronger and climb up the ladder step by step.
During the long journey, she met him.
He was innocent and careless, but he couldn't help but fall into her world.
His love is close at hand, but her heart is far away
Where should he go?
"It turns out that you are the most cruel one."
The unforgettable love is set in the abandoned city.
