I'll start it with this Series being labeled as BL. I do think that they used BL as a click bait. It's more like bromance or friendship and brother hood . That's the first thing I want to emphasize

The theme and story are very interesting and good, and it will have additional star if they really make it a BL. It's all about crime and investigation. A mafia leader or Yakuza and a police officer who joins together to solve a certain case of missing person that will soon lead to reopening a case happened in the past. With the case happened in the past they will try to solve and investigate it and will open memories that hunts them.

The characters are well aligned to the actors, they have good acting and chemistry as well.

I will summarize it, First episode and nearly final episode were all about investigation, the process of knowing the truth is slow and in final episode they explain everything that happened in the past and THEY ENDED IT OPEN.

ITS MORE LIKE THE EVERYTHING THEY DID IS USELESS, NOTHING HAPPENED. ITS A WASTE OF TIME I THINK, THEY JUST USED THE BL CATEGORY AS A CLICK BAIT TO ATTRACT VIEWERS.

VERY DISAPPOINTED

Another thing that idon't like is the repetition of flashbacks, well I get it that they want to comemorate or show the past but I think they overdid it, they simply repeat the flashback with the same scene and it kinda annoying because they should at least show different angle or different viewpoint.
