This drama does not solely focus on love between a man and a woman. It's a story about relationships between people with mental issues, portrayed in the most realistic yet beautiful way possible. The brotherhood between Moon Sang Tae and Moon Kang Tae will make you laugh and cry, and it makes you think about your own relationship with family members because you sometimes will see yourself in the character of Kang Tae. Kang Tae, no matter how normal he looks, has his own mental issue and Ko Moon Young slowly heals him, just as he slowly heals her. The soundtracks are absolutely fantastic, all of them. I am enjoying the drama a lot and find it very refreshing among other predictable Korean romantic dramas.
