The age gap for the actors is very concerning, but also the age gap within the plot is also very uncomfortable. The basic premise that a 15 year old has been essentially living in isolation for her whole life, means that her mental age is even lower than her physical age. A full grown man swooping in and developing a relationship with such an inexperienced child is really disgusting to portray as a romance genre show.

Beyond that, the actual plot starts with some interesting supernatural ideas, but it jumps away from them very fast and then it loses the thread on most of the interesting plot points.

It is really a shame that this drama made so many bad choices, because Jang Hee Jin gives a strong performance, but it is not enough to warrant giving this drama a full watch
