Unubore Deka

Both are comedy-centric with slight romance stories written by the same screenwriter and starred by TOKIO members. Supporting characters in both dorama also share roughly similar quirky antics. It's just so funny to watch how they all interact.

Both dramas have a certain kind of humor that is enjoyable and have crazy, hysterical leads! Also, both have TOKIO members as the leads.

Both about detectives that fall in love with criminals they should be arresting. Except the genders are reversed.

What's more important love or solving the cases?

The execution styles of both are campy and comedic, although the cases handled in Unubore are a lot more serious.
Production quality and acting of Unubore are overall much better than Bishoku, which makes up for the lower res, since it is an older drama after all.

Both have Nagase Tomoya as the lead and are fairly comedic as well.
