You Don't Deserve My Sister!

I am pissed to the person who claimed to be the boyfriend of my younger sister. I have suspicion that I actually know this person although my sister never mention your name to me or to the rest of our family but I just hope that you will stop this rumor. If you are trying to patronize my sister for your own gratification then make sure that she also likes you. I just want to tell you that other guys will not stop courting my sister just because you are claiming that you are my sister's boyfriend. Dude stop spreading lies okay?
