OMG
It's super steaming hot.
As it handles BDSM, it's kind of like 50 Shades of Grey, but in the M/M and K-version.
The background of the story is Seoul, Korea.
Not only are the NSFW scenes interesting, but the relationship of the two main characters...
I really love Hwayoug being so multi-dimensional.
Sometimes, the main character of a romance tends to be kind right out of a factory or something (rich, good-looking, good-mannered, sexy), but his minor *flaws* make him even more attractive.
The main story is complete in this volume alone, but I can't wait to see the upcoming volumes and see them in other episodes.
My friend from Korea gave me some spoilers, but I really want to read it myself.
