It was very hard to concentrate on the story because of Lee Je Hoon...I mean this guy is a phenomenon. Is acting EACH TIME is flawless and delivered perfectly.
The story as well is a solid 10. Mental Illnesses, if adequately treated, sometimes offer many abilities that others do not have.
The brain allow you to "absorbed" emotions, like the main character superbly portrait.
So the drama starts like a flower bud that in the end blooms.
I adore the cold cynicism of Je Hoon that clashes with the demure yet empowering personality of Hang Ge Ru.
Great show, but a bit more of "light hearted laugh" at times lower the value of re-watching.
When the subject is heavy, inserting suspense or laugh is a must.
