My Step-brothers best friend

My name is Lia Carter. I'm 15 years old. And I'm in love with my step brothers best friend. My mom married this guy, Max, and his son Nash is now my step brother and Nash's best friend Hayes lives with us too. He's pretty cute and nice. We are a happy family until one late night in the house alone me and Hayes kiss.
What's going to happen with Lia and Hayes? Will they tell the family? Will they keep it a secret? Will they fall in love and be together? Or will their family tear them apart and not let them be together?
