One of the best plot

At first, I thought it was somewhat weird about the title and supernatural occurence and all. I even tbought it might be a horror but no! This is one of the best plot that I seriously love so much and would really recommend to watch not just once! Even if this is not a bl series, I would have watch it the same cuz the plot especially the ending is just so good. I really had some hard time predicting how the story would go at first but watching the ending is just something that even I myself can admit although I hate that.
