This drama had one of my most beloved tropes which is the change of identity and of face surgery where our Male Lead thinks his beloved female lead betrayed him. He is a man bent of fury and hatred of the woman he once so desperately loved. He hurt her in all the way he knew to hurt her. It was heartbreaking to watch. He was only digging his own grave and he let his bitterness and jealousy consume him until there was no way left for her to actually forgive him when all secrets were revealed. And that ending....oh god that ending.
