Once again, South Korea hits it out of the park, and does what they do better than any other film maker I can think of. This is a story of a Psychological nurse (Park Bo-Young), her nursing team mates, and doctors who serve the population of folks with Mental Health Issues, ranging from Depression to OCD, Panic Disorders, Delusions, Anxiety and the like. These illnesses are not glossed over but portrayed realistically. In Korea, there is a lot of pressure to perform and serious competition for "First Place", which can wind up being soul sapping and even downright dangerous to one's mental health. No one is immune. Park Bo-Young plays a gentle, nurturing, warm hearted, shining example of a caregiver in difficult circumstances. The loss of a special patient to suicide on her day off creates a crisis point for her, and she must navigate her way back from Depression very carefully with the help of those who care for her. I teared up from emotion several times during this show. There is a little bit of romance, but not enough to steal the plot away. She has two men interested in her. One is a friend from childhood, and one is a Colo-rectal surgeon from the same Hospital. Both of these have issues of their own. The subject of unwarranted fear of people with Mental Health issues is also explored. In many ways, this was an "educational" show, without being heavy handed or "preachy". Everyone who watches will learn more about the subject, as was intended. There are humorous and light moments as well, which keep the story line from becoming ponderous. Park Bo - Young delivered an outstanding and realistic performance. The realism extended to other parts of the story as well. To my eyes, at appeared that the cast did not wear any makeup, which would be a "First" for K- Drama! There is a lot to learn, appreciate, and love in this show, and I urge you to watch it!
