Set in the sun-soaked college town of Westbrook, California, Not Supposed to Fall follows Ivy McCall, a disciplined psychology major, and Asher Reid, a laid-back music student who happens to be her brand-new stepbrother. Forced to share an off-campus apartment after their parents’ whirlwind marriage, Ivy and Asher can’t seem to go a day without arguing — about chores, classes, or whose turn it is to buy milk. But between late-night study sessions, campus parties, and unexpected moments of vulnerability, their mutual annoyance begins to blur into something dangerously close to desire. As they navigate college life, family pressure, and the line between what’s right and what feels impossible to resist, Ivy and Asher discover that some hearts don’t care about boundaries — especially when love was never supposed to happen.
