Okay, I watched this series and for the first time ever in my miserable life, I read the book of an actual movie/Tv show. This is overall, the best BL I've seen, acting and storyline are a 100% superb. If I made a list, I think this series could easily rank among my top 3 TV series of all time. Because of how emotionally attached I am to this series, I even dare to dream that more seasons would come out.
I must add that although Korn and Knock are my favorite TV couple of all time, Bai Luo Yin and Gu Hai are a fierce competition.
