An affair with my husband's son

Selina's POV : 

I never agreed to get married to a man I don't have an idea of. I never agreed to my parents wishes, but in the next few hours, I saw myself in a white wedding dress, still with my sneakers on. 

An impromptu wedding. 

This man I heard is supposed to get married to my sister, and definitely not me. I could remember hours ago, my sister was having that conversation with my parents about the man she was to get married to, but what why is it now me on the Isle.  

A few hours ago...

"He is a nice guy from a nice background, Nala, and I promise you, you will like him." I could hear my mother Jasmine conversing with Nala. I peeped to watch and listen to what they were saying, instead of cleaning the house as I was expected to. 

Nala had her leg on the other, looking like someone who might burst in tears soon. "Why should I be the one to marry him? What about Selina? She is also old enough to get married. Why me? What offense did I commit?" 

"Selina is..." Father wanted to say something, but Nala cut him off before he could. 

"She is what? She is over eighteen already. Why can't she get married? Why do I have to be the one to pay for your debts?" 

I heard mother sigh, and quickly I moved away.  

I heard Nala is getting married to pay off my family's debts. She doesn't know the person she is getting married to, and I do felt pity for her. 

Turning to peep again, I saw her standing right in front of me, glaring hard at me. 

"You were eavesdropping. Who do you think you are?" She scowled angrily at me. 

"I am so sorry. I shouldn't have."

"Is that an attempt to make fun of me? Oh!" She exclaimed, "I will be getting married to a strange man, while you do nothing, but peep around like a dirty rat. You sick girl!" She snapped at me. 

"Sorry." I apologized again. Of course she doesn't like me, I don't know why. My parents also treat me badly, I also don't know why it is so. Crazy right?

But they are still my family, and every affair in the family should matter to me too. 

"If you are truly sorry, then run along. You are not needed here, because the more I see you, the more I get angry so much that I could kill you. Scram!!" She yelled angrily, and quickly, I ran away before she could actually lay out her anger on me. 

I ran to the kitchen to continue what I was doing - cleaning. 

I was busy cleaning when I heard my phone ring silently in my pocket.  I picked it up, and the next sound I heard was vociferous.

"Happy birthday Selina!!" I quickly took the phone away from my ear.

 It's my birthday?
