I love Leo and Victoria so I had to watch this. It started off pretty interesting but the theme of scientific research won't be for everybody. I also didn't think I would like a slower, more serious drama but it really captivated me in the beginning. Then it began to drag and the characters became so frustrating. One of the main frustrations I had was how, for how intelligent she is, the female lead always had to be one step behind. Honestly, I regret spending my time watching this drama. The acting was good from what I can remember. Victoria is getting better and Leo was great as usual.
