I read the manga before but wasn't that enamored by the manga but the movie storytelling style actually gave this story way, way more depth than the manga. The themes of the manga are shallow compared to the recurring life and death theme in the movie.

The mood of the story is very dark and suspenseful compared to the manga which sort of gave everything away by chapter 3. The small details the director(s) added elevated the story: for example, the music hummed by Yoda, the rooftop, the bottle of poison...etc all linked back to Yoda's trauma with missing the sign of his boyfriend's suicide.

The movie was done very artistically... I didn't feel like it was simply a porno or erotic movie. The sexual pleasure is something both characters used as a mechanism to feel alive.

Acting was good (especially Yoda). He was nothing like the manga character ... very domineering and scary yet also so sad at the same time. The somber piano music is appropriate.

Overall, I think this was a very good, dark BL if you are into darker themes. It explores some dark themes such as deaths, suicide, and depression.
