Only half an hour, but it was succinctly utilized and on point. I have no knowledge about the original novel and have never watched any adaptations.
For a clip that was released as a part of a variety show, it had more impact than many billion dramas that China releases every year.
It has an overall simple production, and I've come to slowly recognize the directing style . The cast did an excellent job, particularly the two male leads as it was between them the game of 'throw-the-ball' was fought. The Female lead was good to, but as the story centered around her without her being aware of anything happening, she had only a few emotional moments.

The ending is what I find truly unforgettable. I paused for a moment and it made me confused. What or who exactly was the demon after? Why was he so cruel?
Definitely a must watch if you just need an escape from reality.
