I am an ordinary person, but I was transported through time because of a murder case. Unexpectedly, ancient times were not peaceful, and murders occurred frequently. At this moment, I am an outsider, and I don't know whether I will become someone else's pawn in the next moment, or something in their pocket. Only by making calm judgments at all times and taking steps step by step can we protect every inch of ground under our feet. In this time and space that does not belong to me, even if I experience life and death, I am still waiting for someone to hold my hand and promise me that when the scenery is clear, he will accompany me to watch the long stream of water.
