Kei×Yaku: Abunai Aibou (2022)

Both dramas feature a policeman and a member of the Yakuza who are allies in the quest to find out what happened to a woman they were both very attached to.

In Ouroboros they're siblings in everything but blood, and in Kei x Yaku what they have is closer to a romance.

It's the story of two men on different sides of the law, too. The atmosphere is similarly dark, and it is directed and acted well.

It’s a thriller, in a medical scenario involving human organs trafficking. This is a BL, warning for those who are not into this genre. But plot is very good and with great Prodn values.
