There is a legend going around Hongbo Entertainment.

The digital piano that was rented by their golden child Gan Qingqing is possessed by a demon!
Firstly, Gan Qingqing never sleeps well.
Secondly, Gan Qingqing fell into a coma and has not awoken!
Thirdly, the piano plays on its own even when it is not plugged in to power!!
Ah, scary!

In reality, Gan Qingqing was irresponsibly composing music at all hours of the day and without proper sleep, eventually collapsed. As for the second and third point? Qingqing woke up to find herself out of her body and is now crying shamefully in the digital piano.

"Hey, get out of there, Gan Qingqing." His tired face is crumpled in a sour expression.
"???"
"You're so noisy crying in there. Come here instead." He opens his arms.
"Who are you??"
