This movie depicts certainly not a standard BL story. It is dark and gritty with some strong psychological elements. After watching it, I discovered that it is an adaptation of a manga of Setona Mizushiro that I loved to read. It does not fully adapt the whole story but it does a great job taking some of the most interesting elements and putting them together to form a cohesive and captivating story. I think the storytelling would have benefited of a bit more time for some of the developments but overall I was quite satisfied by what the movie achieved, especially in terms of character growth.

I think the chemistry was pretty good between the two main actors. You can feel the intense obsession of one for the other as well as the indecisiveness of the other regarding his feeling for the former. There are numerous sex scenes which all have a purpose in terms of characterization and development of the relationship. Nothing feels gratuitous but it is instead meaningful in regards to the evolution of the protagonists. The actors really went for it and worked very well together, making those scenes raw and really believable.

The production value was good with a lot of little details in the filmmaking allowing the viewer to understand the evolution and change in the relationship, not only because of the script but also even visually through the sets and accessories and how they evolved within them. There was some moments were I felt the editing a bit abrupt, especially jumping between some scenes toward the end, but nothing too distracting for the understanding of the plot. The soundtrack was fitting the dark theme of the film without really being memorable.

I would recommend this to people looking for a mature BL story. It is a dark story involving a lot of heavy topics, toxic elements and it can be triggering in the way the relationship forms itself. If you enjoyed this movie, I would strongly advise to give a chance to the manga from which this movie is an adaptation.
