Wen Xiaoxiao was so sleepy that she fell down on the table. When she woke up, she found that she had turned into an air conditioner and hung on the wall of the living room of her boss Xu Yan's house. He was investigating a leak case, and she was the one who handled the manuscript.
What's even more troublesome is that she will randomly transform into various things - keys, microphones, surveillance cameras, and desk lamps. Every time he changed, he was one step closer to the truth about his parents' disappearance, and also one step closer to being discovered by him. She didn't know what would happen tomorrow, and she didn't know if the person who was tracking her would be the only one she could trust. Every time it changes, it is one step closer to the truth and one step closer to being discovered.
Concept: People will be trapped at all levels, visible and invisible. She was trapped in the air conditioner, and she was trapped in "forget it". Move forward, not because the road is bright, but because your feet have been lifted.
