The detective and a criminal path. Both of them are bored of... well everything. They used to go to the same high school. They kinda fell for each other there but nothing happened. They met up as adults by accident (the criminal was walking out and met a homeless person (a cop in disguise) and took him home cause he recognized him. The criminal ended up secretly helping him with investigation. The detective figured it out anyway. They started to date basically. Now they work as a team and nobody knows it.
