I have watched over 30 BL dramas/Lakorns so far and this show is the worst. I don't know what the rating of the show was, but it had to be for a general audience. For a show about romance, there was no physical affection at all - the closest you got was drunken mistakes and almost-sexual assaults. The main character Yihwa is not an independent woman, but a prude, who refuses the advances of others, even when she likes them. Cho goes from being nice to acting like he is going to rape Yihwa over and over. Korn and Knock are the most poorly written gay couple of any series outside of What the Duck!. They argue and fight physically as a way to avoid having to kiss on screen. The series had ghosts and a woman with super powers, and why would four separate characters all be fighting over Cho? He is cute, but there were so many other cute guys in the show, including Tanguy.
The credits on this site don't even mention the actors who played Being and Martin, but they were a nice couple on the show. The episodes were too long, nothing happened and the music was bad. The ONLY reason to watch this thing is because everyone is very attractive. The women are beautiful (especially Beauty) and the men are hot. Maybe it's better to forget this show exists.
