I have watched many many kdramas and out of all of them this one is my most favorite. Literally everything about this drama is perfect from acting to story to OSTs to cinematography. Most people who do not like this drama, they don't like it because they fail to understand the deeper meaning behind almost everything in this drama. This is not a typical romcom type drama with a crazy plot or a lot of plot twists. This drama is meant to address mental health issues and it does a very good job at doing so. The character development of all the characters in this drama (even the side characters) was flawless, which made me attached to all the characters. The OSTs fit the scenes so perfectly that they did not seem awkward or unnecessary at all. I cannot praise the acting in this drama enough because it was amazing. I don't think anyone else could have portrayed the roles of Gangtae, Sangtae, and Moonyoung as beautifully as Kim Soohyun, Oh Jungse, and Seo Yeji. Many people like to judge the plot twist in this drama but that plot twist is left up to interpretation and has a valid explanation that is related to mental health in general. I know that a lot of people think that this drama romanticized mental illness but I personally feel like they humanized individuals with mental illnesses as there is still a huge stigma associated with having a mental illness in many cultures (Korean culture being one of them). Overall, I think this drama was just amazing and it deserves the hype it got.
