1. Nano, the heroine, is neither a human nor a ghost, but a mysterious existence that is immortal and infinitely reborn, so she is also called "Fujiang in Thailand".

2. At the beginning of each story, Nano will enter a new school as a transfer student. As long as there are people with evil thoughts in this school, she will be attracted, and then the darkness hidden in people's hearts will be excavated again and again, and the amplification will be infinitely induced. Finally, people will pay the price in extremely extreme ways. So many times, her existence is like a mirror, reflecting the ugliness hidden in human nature.

3. In fact, even if the hostess doesn't induce others to go into darkness, the seeds of darkness have already taken root and sprouted in people's hearts, and the appearance of the hostess is at most the fuse to aggravate the release of darkness in human nature, so that the audience can look directly at these problems more deeply and clearly. What's more, when Nano exposes the darkness of human nature and tempting crimes, she will also give others a chance to choose again. For example, she will always ask "Are you sure you want to do this?" And so on, so the person in the corner of "Nannuo" can be said to be both good and evil, but she does not represent the three views of human society, which is something that the audience who follow the drama should pay special attention to.

4. After all, Nano is not the embodiment of the so-called justice. In the words of netizens, she is the daughter of Satan and the demon in the game world. The significance of her existence is not to punish evil and promote good, but to tell you what is right and wrong, but to look on coldly and laugh hysterically after amplifying the evil thoughts of human nature, which implies irony. And there is no absolute justice or evil in this drama, but only human nature.
