The narrative delivers several major twists that dismantle the initial corporate setup:
- Grandpa Nam Gun-ho’s Deception: Corporate patriarch Nam Gun-ho faked his advancing dementia to test board loyalty and secretly bankrolled the AI research in the Czech Republic, knowing all along that Nam Shin III was an android.
- The Corporate Conspiracy: Ruthless executive Seo Jong-gil orchestrated the original truck accident in the Czech Republic to assassinate human Nam Shin and seize control of PK Group.
- Human Shin's Antagonism: Upon waking, human Shin is consumed by jealousy and betrayal, partnering with Jong-gil and using a manual override module to force Nam Shin III into violent acts against So-bong.
- Laura Oh’s Fate: When Seo Jong-gil attempts to crush Nam Shin III under heavy construction barrels while the android is disabled by the kill-switch deactivation process, Dr. Laura Oh pushes him away and is fatally crushed, acknowledging both as her beloved sons before dying.
- The Climax and Epilogue: Framed for Laura’s death, Nam Shin III protects human Shin by absorbing gunfire from Jong-gil’s hitmen and plunging into the ocean. One year later, Jong-gil is imprisoned, Ji Young-hoon leads PK Group with integrity, human Shin travels the world to heal, and Nam Shin III is fully restored, reuniting with Kang So-bong on the beach with the newfound ability to shed a tear.
