KRiQIYI +3

The drama follows Nam Sin III, an android created to look exactly like a human heir, who is forced to take the place of his real counterpart after a tragic accident.

Nam Sin, the only son of a powerful conglomerate family, is separated from his mother O Ro Ra at a young age. Devastated by the loss, O Ro Ra, a brilliant expert in brain science and artificial intelligence, creates an android modeled after her son and raises it as a replacement.

Years later, when the real Nam Sin, now a third-generation heir of the PK Group, falls into a coma following an accident, Nam Sin III is brought out of hiding. Tasked with pretending to be human, the android must navigate corporate power struggles, human relationships, and emotions he was never meant to possess, all while hiding his true identity.
