Arranged marriage with a stranger

I dragged my father into the kitchen to talk about this- this stupid agreement. I will not just keep quiet and let them do what they want with my life.
"H-How could you do this to me, Daddy? I said with tears in my eyes.
"I'm sorry, darling. I made a promise to him". He said with a sad smile."I cannot break it."
"B-But...". My face was drenched with the tears and it started falling to the ground.
"No buts, now stop crying." "I am your father and I know what is good for you, Do you understand?"
I simply just nodded because I knew arguing is not gonna work against my dad. He was absolutely serious.

'Him' refers to Alexander Conway, my father's childhood friend. I didn't know him at all except that he came with his wife to my house on Sunday morning to talk about the 'promise' my father made to him. I had to marry their son who is 4 years older than me.
I am only 21, not ready to get married and settle down. I felt like someone just buried me alive under a river with a huge stone on my mouth, preventing me from talking and expressing my opinion when i got the news.

I mean, its not everyday you have to marry a complete stanger.

My name is Paris Lockwood. My mother always dreamed of going to Paris so she named me that way.
I am 21 years old, cheerful yet sensitive and I cry too easily. People tease me because of that but I am used to it now. I have a beautiful and caring mother who loves me a lot. My father is very entertaining and loving but he gets extremely serious if it was related to business. But despite that, I love him a lot. I have a older
sister who cares for me but does not lose the opportunity to tease me sometimes. I am very timid but bold enough to make choices on my own. I studied business and have a lot of friends.

I had a happy life but god decided that I was not satisfied and brought this to me.
I have to marry a stranger.
