This is actually a very light horror themed series, for those who are hesitant to watch due to its horror content you may watch this. For some who wanted to watch this because of 'BL' thing yeah there is also, as I posted in the comment section, do not be decieved by the negative comments and poor ratings, this is quite a good series, and I really like the progression of the story and how it ended, but some casts acts weirdly (lol) the prosthetics and the make up for the ghost is not convincing, but still it's Okay.
You can watch this in YouTube. Thank you
