The emperor Yu-Jun was in hiding for a hundred years and became the emperor once again. He lived in agony because when Eun Won died a hundred years ago, he finally found out that she was framed, but she was already killed by him.
When she said her last words, she cursed him to live immortal life. He would never find any happiness until she was born again. He searched for her every day, but there were no signs of her being alive.
He still had hope in his heart until he finally gave up and waited until she founded him. He wanted to tell her that he was sorry for not believing her back then.
