This video is about Freddie Mercury's ex-girlfriend who broke up with him after being engaged and living together for 7 years. Freddie dumped her because all she wanted from Freddie was just his money. And also, she was the one who started the whole gay rumors about Freddie. Freddie Mercury was a Parsi Zoroastrian, the most anti homosexuality religion on earth. That's why he felt so insulted and got really mad at her.
Although he dumped her, Freddie still couldn't forget her and felt so guilty for that. Then he wrote a song called Love of My Life, dedicated for his ex girlfriend.
And at the end, Freddie left all his fortunate to the woman in his will, saying "you would have been my wife and it would be yours anyway", and died peacefully.
This story and this song are one of the evidences that proves that Freddie Mercury was not gay.
