I really don't know. It could be inspired by real-life incidents but transformed for dramatic effect. You might want to check with the creators or do some research to get a clear answer.
The ending of 'The Fault in Our Stars' is truly poignant. Augustus passes away, and Hazel is left alone. However, she doesn't let this completely break her. Throughout the story, their love was so intense and special. And after Augustus is gone, Hazel has to find a way to keep going. She reflects on all the things they did together, like their trip to Amsterdam. The story's ending is about Hazel finding her own way in a world without Augustus. She is sad, of course, but she also has a new understanding of life and love. She knows that their love was something precious, and she tries to make the most of her life while still cherishing the time she had with him.
Well, without more context, it's difficult to say. It might be a novel where the main character is always in the right, or it could be about a utopian world where no one is at fault. Maybe it's a new take on the concept of faultless existence in a fictional setting.
It's possible that 'Is My Fault' has some basis in reality, but Eminem's music often blurs the lines between fact and fiction. Maybe it was inspired by real events but transformed through his creative process.
