Warning: underestimating mental illness…?
"Dark Caves and Fields of Lights"
Ever since the dark cave in the Digital World, Sora had a problem: at points in her life, she fell into a hole where nobody could get her out. She once lost a part-time job during high school; it became so bad she became incapable of properly talking to customers.
However, Sora was never afraid. Because "nobody" was not correct. Someone could always reach her, even in her dark hole. Jo was always capable and always willing to help her back into the light.
She never feared her inner darkness, as Jo's reliable light is always ready to save her.
