The storyline is very good and unique, I really like the mystery genre like this. and this is also in the spiritual world, so there are ghosts in it, very tense!! The actors are also very handsome and beautiful, their acting is also so natural that it makes me feel scared, sad and happy. I will rewatch this drama again and again. This drama also has a touch of bromance in it, even though I feel scared when there are tense scenes, the main characters always have something sweet between them. I like it very much!!
