The most ridiculous thing I've seen in this so far was that oxygen circulation system
I think as ridiculous as it was it's main purpose to show how everyone is breathing the same 'high class air' they have different worries and ambition at different times.
Many elements make this show: the high-end production design, the great acting, the set, beautiful outfits, styles, and even the OST, which sets the tempo and brings character to the drama. Kim Seo Hyung elevates Mine with her performance. She thoroughly embodies the layered character of Seo Hyun so brilliantly that without her, Mine wouldn't be as good as it has become. I love how our three strong women worked everybody from the Chairman to the nun and the police. They had it all planned to the "tee," as they say. This show clearly articulates that everybody has secrets — until they get caught or maybe not; we shall see.
The OST's are wonderful, Whenever I hear Dear Son, my Heart Wrenches in any situation, Whenever I hear "This is Mine", I feel thrilled and energetic and can feel the Power. Also "Mine" by ID is amazing, especially the lyrics "The more we get, the more we want to have in myself"......... All the other tracks are equally amazing.
The police, when Han Ji Yong died: OMG There's a brutal murder. Let's find the killer...
