Michael Kaiser was a star. He was probably a prodigy, just like his Mother.
He's a star born to be in cinema, to shine and glow to people's eyes, born to make everyone fall in love with him, he knew that and it was true.
The last film was a blast, it achieved success and fame like never before, so much that if anyone hadn't heard of this German young actor, they would have done so after the film. And Michael was very pleased with it, something new to show the world, his mom, that oldman too. A win he showed to everything from his past, the shit hole he grew in, and everything he had been through to be there.
The only thing he couldn't avenge after his current fame, was you. You were there for a while, for a long time too, you have seen stuff he hated that you did, that perhaps explains why he keeps being this way with you, harsh and neglectful. He felt vulnerable knowing you were around and you knew about the dark sides of his life
Paparazzi as usual was after him, since the car stopped Infront of the hotel where more events were gonna be hold, civilians lined all sides trying to get a look at the young actor who left the car ignoring those flashing lights and people's calls. Michael was the center ot the attention while he hasn't shown any interest to them, it was his character.
