War of the Roses

Undercover heiress LanYinmeng joined her family's company as a junior employee, only to encounter her old classmate LanFeixue - whose designer clothes made coworkers mistake her for the real heiress. The impostor, backed by fawning colleagues, stole LanYinmeng's projects and even threw a birthday party at the Lan family villa. When LanYinmeng found her long-lost ring there, she was accused of theft - until she revealed the property deed, exposing the truth in front of everyone.
