I loved everything about this drama. The main leads showcased the pain, fear and joy of their characters so well. This drama also tackles relevant social/medical issues of people with mental illness and special needs. It has a deep mysterious story that gets you hooked. The music and the graphics are also on point. Seo Yeji and Kin Soohyun's chemistry is off the chart!! Kim Soojyun"s character is timid, caring and selfless while Seo Yeji's character is the total opposite. Also, Seo Yeji's character Ko Munyeong has the BEST wardrobe.
