All Lies

Lisa is a young billionaire CEO who inherited her father's company at 14 after his death. During that time, her family completely fell apart. Her mother had already been emotionally distant and was secretly cheating on Lisa's father while he was hospitalized. Eventually, her mother left Lisa and married a wealthy man who later becomes Lisa's corporate rival.
Unbeknownst to many, Lisa's mother already had a child with her new husband when Lisa was 8 years old. This means Lisa's family was broken even before her father died, but everything was hidden under lies and excuses.
After her father's death, Lisa fully takes over the company and grows into a cold, guarded, and feared CEO. She doesn't trust anyone, carries emotional trauma, and believes people only betray for money.
Lisa also lives under constant threat-someone is trying to kill her and take her wealth. Because of this, she secretly carries a gun and becomes highly paranoid. She suspects her mother and stepfather are behind everything, so she uses her most trusted friend as a spy to monitor them.
