Love is war (boyxboy)

Hi, hey, howdy, hallo, I am Stefan (don’t say oh-em-gee that’s that one guy from that one show with the vampires) I am 17 years old and a senior at P-L-B high school. I am basically your average teenage boy except from one thing, When I was born I was cursed by a crazy lady who likes to be called a ‘witch’.
When Stefan was a inside his mothers stomach a 'witch' cursed him. He could only fall in love with his soul mate. So what happens when Stefan gets two soul mates one a girl one a boy, but more importantly which one will he choose?
