I've been thinking of BRILLANTE PV as it reminded me of something but didn't know what was that. It wasn't any particular clip or movie or anything, something rather like a scenario. I was thinking about her way of shivering and the guy who kept sing with the same face and now I know. You may laugh but it slightly reminds me of Nero's death from Quo Vadis (just the story).
Here's how I understand the story, you don't have to agree
In the beginning Ayu's sleeping in the arms of her personal advisor, a person who is like second family, she trusts him no matter what. Don't you get the feeling that his singing sounds as if he was repeating "Do it, you have to do it, you have no other choice". She wakes up tired as if she has been thinking about sth for a very long time or made a fatal decision. Her face is sad and she looks as if she's about to start crying, while the guy is self-confident and sometimes even smiling, almost saying "there's no other way, you are strong, you can do it". He even shooshes her at some point as if to calm her.
In the meantime, scenes show Ayu walking and dancing among her "army" / people. This may be the past since her face is calm and she's confident. It may show how great emperor / boss she used to be, the guys do their exercises, however, some of the guys look at her as if they knew she's about to do something wrong (something they won't like), rumors are being spread, etc.
The interlacing scenes with Timmy show Ayu being totally lost, she already did something wrong, her army revolts. She escapes to the highest point, her throne and they climb after her. There's this beautiful contrast between the scenes with the red sky and her people standing around her and protecting her (the past) and the scenes with black sky and her people trying to reach her with angry faces which suggests bad intentions (the present).
Timmy, still being next to her, still tells her to do it and now we can assume that he wants her to commit suicide, the crowd wants to get her but she finally says she will do it herself (or he screams that for her, I still cannot say whether he pushes her into the crowd or not, seems so at first but then he seems to scream NO at some point and stretches his hand in her direction).
She gets back on the trone and then understands that she had been tricked by her advisor and he was never a person she could have trusted. She's face to face with him for a short moment but before she manages to ask or do anything he kills her.
