I just completed watching this tonight.
What a performance for all the actors and actresses! I love how powerful each episode are. Special mention to Seo Yea-ji, she is such an amazing actress and she is so beautiful to look at. Park Byung-Eum is such an amazing actor. I can feel how deep their love was and at the same time how conflicting it was. Yoo Sun, although playing an antagonist, she gave such a beautiful performance too.
Actually, all the actors in this series were so good. Hope to see them again in another drama.
