I watched this drama till the end expecting it to pick up at some point but really the best episodes were 19 and 20. With such great actors don't know what happened...the couple with Kwon Sang Woo had no chemistry, no pizzazz am really disappointed...he being one of my favorite actors. I wanted to see how he performed in this role as a doc. The other couple fared better. Too much time spent on technical jargon and I got bored and uninterested. There was no cohesion in the whole thing. So sad the turn out of this drama. For me it was a waste of time.
