Mentions of ptsd, murder mechanism & homophobia. The story is about two detectives. One joined solely for catching his late lover's murderer(he was a sociopath, I think). But, when another case similar pops up, his ptsd starts to act up & his co-detective was dragged to sort it out through "physical means". This would've been one of the best in terms of story if the relationship was elaborated at the end. But, the story just stopped right after their solid relationship was established.
