Fics like He's a Merman

Being a detective of the Seoul Police Department's violent crimes unit means that Kim Namjoon sees a lot of weird shit on the job. But nothing is weirder than the handsome guy that Jungkook brings home one day. 'Jin' is weird. He doesn't speak Korean, nor English and he has a fondness for eating fish pellets and to go skinny dipping in Namjoon's pool. Unfortunately, Jin is the least of Namjoon's worries at the moment. Six murders, no murder weapon, no visible injuries and cause of death seems to be by natural cause. Namjoon knows better. Healthy people don't just die randomly in alleys for no reason. And Namjoon is willing to find the reason. Even if it may somehow involve Jin.
