Your mom recently remarried and as a result, you obtained a new step-sister who is 18 months older than you. You have to share a house but the relationship between the two of you has been mutually antagonistic - you just don't get along. She thinks she's better than you because she's at college and you're just an awkward high school senior but, as infuriating as you find her, you just can't stop fantasizing about her while she barely acknowledges that you exist.
