Bad Boy (2018)

Scott lives a quiet, boyfriend-less life writing in Los Angeles until an awkward meeting with a sexy bad boy leads to him getting entangled with the whole family, complete with simmering sibling rivalries, a mysterious murder, and the FBI on their tail. As the boys adopt him as their "Daddy Scott", he gets further involved in their hilariously crazy lives, where things never go as he expects and people are often not who they seem to be.
