If you've seen the trailer, you may think this is a mystery/horror movie but don't be fooled. There are two arcs in this: first half fools you into thinking its horror and the latter half is emotional and a real tearjerker.

Basic rundown of this story without spoilers: the female lead notices her neighbors being weird and tries to find out the reason. There is also a strange light shop down the street that she is suspicious of. She works with her boyfriend to discover the truth. The director does a good job using color to portray the mood of the scene- using dark contrast for the "horror" and warm tones for other scenes. Additionally, the metaphor of using lightbulbs to represent human life is the heart of this movie. Characters enter the light shop to get their lightbulb, others don't have one, and some choose to give up their lightbulb.

You can tell they had a good budget and spent a lot of effort and time to create this movie. The transition between scenes and flashbacks was so smooth, you get pulled into the story even more.

There were a lot of familiar faces in this: Zhang Ruo Nan, Bai Yu Fan, Zheng Kai (cameo), Sun Qian, and Liu Yi Jun. They really embraced their characters. Bai Yu Fan and Zhang Ruo Nan's emotional scenes especially broke me. I was bawling at the end of the movie.
