My FAVOURITE Korean drama of all time!!! The staring eyes part happened a lot, and I loved it. Their chemistry is above all, and even their faces are quite similar to each other. I love them so much. The story is very touching and makes me cry sometimes. They also show the patient's story and how they improve themselves towards the end of episodes, which is such a great touch. This drama's OST is the best I've ever heard. It made me repeat the OST all the time I felt sad and lonely. The greatest one All of the leading characters play their parts so well. Even though I'm a bit annoyed with the second female lead, through the end, she's becoming more tolerated and quite cute. On top of that, the Sangtae character is the best. A clap for actor Oh Jung Se for playing this character very well. I have an autistic cousin, and it's quite the same with Sangtae.
