The half demon girl

Opening my mom's diary,i kept reading page after page and then i got shocked...Oh sorry maybe you don't understand what's going on,but let me start all over from the beginning.
Hi am Nathalie Booker,i was born without a father,u wondering why and how,the only thing i know and my mom told me that he left when he knew she was pregnant with a girl,yeah he left just because i'm a girl,i have an older brother actually,he is so kind to me but sometimes he acts so weird,my life was going pretty good,i had a pretty big home, a wonderful mom,and a beautiful brother and grandparents,it was all going normal,until the day i saw my mom holding a book and crying,i tried to ask her but she hide the book at the second she saw me,and she said that's everything is good,i wasn't sure if she was lying or not,but i had always doubt that's something is wrong,and i knew taht my brother know about it,but i was never brave enough to ask him.
Since then,i heard crying noises everynight,but i never knew why she is crying.
After a month,mom and my brother had a work to do,they left me alone at home for almost a week,i decided to go check the book my mom was holding that night,yes i couldn't forget,i still remember the book's cover,i went into my mom's library and i found that book,it was so weird ,it's not like any other book,it was my mom's diary,but what's in this diary that will make my mom cry?it is something about my father?i started reading nothing was bad tbh,until i started readin the fourth page,and yeah it was about my father,or should i call him THE DEMON, no it wasn't just a nickname he is literally a DEMON,my mom died when she was giving to my brother,she wasn't a good woman or a good wife to my brother's father,so she went to hell,but she was really upset she really wanted to change,she wanted to see her son,she was waiting this moment her whole life, she asked the demons if there is any way to get back to life,they didn't care about her tears and rejected,they all left but one,he was so kind to her,he proposed help he can get her back to life but under one condition she should marry him,and get pregnant from him,she was so confused,how is that even possible?but she accepted at the end,and they secretly married.
Since he could turn into a human shape,he was always visiting her,the weirdest thing is that they had SEX,i don't know how but they did,my half brother's father found out, he thought she was cheating on him with another man,and he left her with his son,when my mom got pregnant my demon dad kept visiting her,but the other demons found out and they sent him to the Underjail,so when i was born she had to lie to me .And now i knew am Half demon girlention a user
