A very confusing narrative plot, but with very profound features. It must be said that the theme of sexual identity is increasingly present in Korean dramas, a giant step forward in a closed and very "homophobic" world. Here the theme of obsession was adopted, to deal with something dramatic, identifiable. The two protagonists are very in tune, the classic love story of two very different people, but very similar to each other. Then there is the fantasy component, that is, her ability to know whether the person in front of her is telling a lie or the truth. The obvious ending, and the extra episode that wasn't needed. But all in all, she wasn't too bad, in fact quite the opposite. I know Kim So Hyun well, loved by the undersigned in every interpretation of her. Most of all, "Who are you", which deals with the topic of bullying that is so dear to me.
