Let's not let the memory of the earthquake fade.
The heroine, Frill, has left her heart somewhere after a certain event...
She knows this herself, and has been living each day aimlessly.
When she dreams, someone calling themselves the "Guardian of Dreams" speaks to her...?

After finding an old teddy bear, how will Frill, a slightly selfish and modern heroine with no particular dreams, change?
