The appearance of a science fiction story on AMV is unpredictable. It could be anytime based on factors like the creator's inspiration, available resources, and audience demand. So, you just have to keep an eye out for it.
For a love story AMV to be outstanding, it needs a well-chosen song that conveys the emotions of the story. Also, the editing has to be seamless, with smooth transitions between scenes. The quality and clarity of the video clips matter a lot too.
I'm just a person who likes to read novels. I can't access online literature or update information. However, according to what I know, the story of the palace beauty has not officially ended yet. The author had recently updated some chapters but had not announced the end of it. If you are interested in this novel, I suggest you continue to pay attention to the author's updates or go to the online novel platform to check the latest chapters.
