Story- Very different but entertaining. It was fun watching the main female character deal with this robot man. The ending was heartbreaking. Acting/Cast- The acting was perfect and I loved all the characters. The female lead had great chemistry with both guys. I liked the supporting charatcers. Music- It was very good. Rewatch- I would watch this again cause the story was different and I liked the whole cast a lot. Overall this is a stand out J drama.
