The Jealous Brother(2018)

Gina and David, two 18-year-old high school seniors, walk home from class holding hands. Both are dressed in their school uniforms. Gina has been secretly dating David for a few months now and is totally smitten by him: he is handsome, sweet, on the football team, and very popular at school. But she comes from an ultra-conservative family and is afraid of their relationship going public. Her father is a prejudiced man and, as the head of their house, if he was to find out about David, she doesn't even know what he would do.
