Saved Amnesiac Tycoon, Then My Identity Was Stolen

The female lead saved a fallen tycoon, only for her stepsister to steal the token and take credit for her deed. After losing his memory, the male lead mistakenly protected the false savior and personally pushed the real benefactor to the brink of despair. Instead of begging for justice, the female lead retrieved the truth step by step with old scars, exclusive prescriptions, voice recordings, vehicle wreckage fragments, and witness statements from villagers from that year, reclaiming everything that belonged to her.
