This drama is absolutely without doubt a solid watch for everyone due to its overall positive tone and superb production quality.
First, I would like to commend the casting of Woo Young-Woo. The portrayal of an autistic person is thoughtful, accurate and full of love. Clearly, there was a ton of thoughts and consideration that went into the research and development of the character and the result was sublime.
The drama balanced quite nicely between the tender romantic moment, the traumatic experience of an autistic person and the intensity of the court scene. In addition with good dialogue and well-paced scene, the writer and director created an enjoyable and satisfactory watching experience. However, I think that the story got quite lost after the half-point mark. But in the end, the ending was a good and fitting conclusion to this ark of the character.
However, I find some of the repeated scenes, such as the photographic memory, the sudden epiphany or the monologue, quite a cliche but that's just my preference.
All in all, I love this drama :)
