Back Off! I'm the CEO's Sister

After years away, the first day Ashley returns to work at her brother Liam's company, she is misidentified, humiliated, and harmed by Liam's fiancée, Erica. Despite Ashley repeatedly telling Erica the truth about who she is, Erica refuses to believe and escalates her abuse of Ashley, until Liam personally confirms her identity. Erica then collapses, begging for mercy, but is ultimately fired and sent to prison.
