I will start this review with saying that I am not overreacting by giving it a full 10. And there will be no spoilers in my review. First of all, as you start the drama you won't know how amazing it will actually become after a few episodes. The idea of this drama is really beautiful, just as the title says. Will you be able to understand other people's minds and hearts? What would it be like to not feel anything or not be able to empathise with people? The story doesn't only have doctor subjects, it shows the importance of life and the value of understanding people's pain. Secondly, the acting is just incredible. I would find myself from amazement to crying and then to a confusing feeling. I would countinously ask myself "what is he feeling right now?" or "how would be to see thourgh that person's eyes?" Moreover, the music is so perfectly fit for this drama that it will totally absorb you into the world of it. In my oppinion, this drama is perfect from all points of view. You will definetly love it, and even more you will live it with all your heart.
