Teaching My Robot Boyfriend How To Love - Épisode 10

The male lead, a robot, was once the female lead's lover, protecting her from the villain's harassment. However, when the villain discovered the male lead's true identity, he exploited the rule that robots cannot harm humans to blackmail the female lead into becoming his girlfriend. He erased the male lead's memory and resold him to a new owner. The new owner, in league with the villain, altered the male lead's memory to make him hate the female lead.
