So I've seen this movie once and yet it still lingers in my mind. The comparisons between the movie and Alice go along way. I really like Jung So Min, like I'm pretty sure it was her who captured me into the K-Drama world, so obviously it's her works that I comeback too- even Mischievous Kiss.  This movie blurs the lines between dreams and reality, which can make the story confusing, but if you pay attention, truly, it is easy to follow. The scene changes abruptly can get a bit disorienting but I'll say, just don't think to much about it.I watched it the first time, only knowing that Jung So Min was the lead, so do be aware that this is a psychological thriller that does have blood and ghost, and can possibly trigger.
Jung So Min and Hong Jong Hyun have really good chemistry and it's cute how awkward he is because it just shows he's good at adapting to his character. I like how they made him evolve and how you learn more as you pay attention not necessarily through being told.
For how creepy this movie can get, it also if a heartwarming story of first love, family and then its a bit sad because it's also about the misery that family and love can bring about.
