Let me know if you are interested in joining.
Basically the idea is that this younger sister, still in high school, is seemingly perfect in every way. Her older sister, in college, is more of the rebel, has less going her way.
Eventually something happens, and the younger sister gets into a dominating relationship with her older sister.
