A reason why I love this drama to death is because of how lovable and endearing the characters are and also because of the interesting interactions between the characters. Considering that the drama is a medical drama and most of the content is of intense scenes and filled with a lot of medical jargon, the drama is still executed so well that the personalities of each character are able to shine through and you can't help but hope for the best for each character. Some might wonder why people say it is that great after watching the drama but for people who have taste for the "mostly slice-of-life" genre, this is their ideal drama.
