Brothers' Regret, No Forgiveness

Vivian was originally the daughter of the richest man, but was kidnapped by the mafia when she was young and thrown into an orphanage. The richest man mistakenly thought Sapphire was his daughter. Many years later, Vivian was taken home from the orphanage. Sapphire hated her to the core and bullied her in school. She was also framed for murder and went to jail instead of Sapphire. The three brothers were unwilling to believe her, but took great care of Sapphire.
