A truly inspiring Kdrama. I felt physical happiness and satisfaction after every episode. From being oblivious to how mentally unstable people behave to being like them, everything in there made me happy and satisfied to the core. It was very pleasing drama, and some notable points will be discussed down below:
1. Park Boyeong: As psychiatry nurse Jung Daeun. She was previously a nurse from Internal medicine unit, but was switched over to Psychiatry because the head nurse there thought that Daeun was slow, when in fact, she was just empathetic. After she started as a nurse in psychiatry, she understood the depth of her own heart. She understood her own thinking process and her methods of mental defense. The way she portrayed depression and self harm through her own life, it was mind-blowing. She did an incredible job in making us realize that we won't understand how exactly depression really feels unless and until we experience it ourselves. Good job, Boyeong.

2. Yeon Woojin: As Proctologist Dong Goyoon. Damn this guy was the most laid back yet most realistic doctor I have ever seen. From being a patient with severe anxiety to being a total heartthrob, he had everything a woman wishes for in her partner. truly a marvel. I was pleasantly surprised by the fact that he in fact fought for his love and did not give up when Daeun told him to. Very rare a trait I must say.

3. Jang Dongyoon: As Song Yuchan. Okay I have always hated love triangles, it just ruins the mood, like it did in Welcome to Samdal-ri. But this guy, oh my god!!! He set the standards for being the best friend even after having a crush on Daeun since high school. He was one of the most perfect second lead I have come across (the others being Hwang Inyeop from True Beauty and Jung Haein from While You Are Sleeping). He really had the best growth and maturity development step by step through out the series. I loved that it wasn't rushed.

These were the main characters, other than these, all other characters were a perfect blend of happiness and satisfaction for me. Highly recommended. Also this drama actually put forward a very good insight about mental health, depression, schizophrenia, delusion etc. No exaggeration whatsoever. I really don't know why people said that it didn't portray it properly.
