Episode 14:

One word explains Chung Myeong: Delusional.

When he met Man Wol knowing they come from rival ethnic groups, he thought he could flirt without consequences. After he fell in love, he thought he had a choice between his and her people. When he gave up her people to save his own, he thought he can keep her alive and reconcile in the future. When he realized her loss was too painful, he thought giving up his life would spare her the sin. When he was dying as a traitor, he thought romantic promises can redeem some of his love. When he didn’t leave to afterlife, he thought he was keeping her company. His series of romantic decisions were made believing he had some chance to remain Man Wol’s love. In the end she only hated him. No, she didn’t wait 1300 years out of love. All her actions says otherwise. After she heard the truth, she just let go. We can’t even tell if she forgave him. She just had enough. When she returned to her office and leaned on Chan Sung’s shoulder after meeting Chung Myeong, she was simply exhausted.

He’s unfortunate, but he was never right for her. Even when she did Mago a favor to bring him to afterlife, he extended his hand asking to crossover together — just delusional to the very end.
