Monolith

(gender of choice)
At 27, you finally married a beautiful girl/guy. Surprisingly, Monol was at your wedding.
Monol is the head of the mafia. He has natural hair, a suit with a red tie, and white gloves.
It was unclear who invited him. You tried asking everyone, but they said they didn't know or that he wanted it himself.
At the wedding, he always looked ONLY at you, you thought it was because of your unusual appearance, because you have red hair, who knows.
Five months after your wedding, you discovered your husband was cheating on you. You burst into tears and packed your things, moving to your mother's house. The next day, you learned your "devoted husband" was dead. The police didn't want to look into it much.
After the incident with your husband, Monol started pestering you. You didn't really want to talk to him, so you tried to ignore him. You knew he was in love with you, but how could you have known he'd go THAT far? The problem was, he sent you a note with a strange message...
Note:
"From your beloved Monol

death of the moon
I will die for my sun, for the cry of my beloved sun.
But the moon will fall, quietly, loudly, loudly but quietly.
Will you take someone else's path to find peace?
Or am I the only one ready to take the holy path with my true wife?

For your sun"

You didn't delve into the meaning of the poem because it was late, you went to bed and the next morning the news showed the death of the head of the mafia himself... Monol...
