Cães de Tóquio (2009)

The atmosphere in both Tokyo DOGS and Bitter Blood involves comedy, as well a reoccurring villain for most of the episodes. Both also explore the relationship between the two main characters who make up a hilarious duo, as well as between them and the supporting characters (their team). Both also focus on the characters' roles as detectives. If you love one, you'll surely love the other!

Both are Police dramas speckled with comedy and serious moments.

Both have a circumstance where two police men who are completely different (one easygoing and one serious) from each other have to team together to solve a big case.
Both have only speckles of love in them and there is a lot of comedy for both of them as well.

Similar shenanigans of the seemingly cold male leads (bodyguard/cop) trying to protect the funny female leads being targeted by her enemies.

Oguri Shun and similar detective story. Cracking cases together and finding to catch the killer of a loved one

The female lead is played by same actress

Mystery crime thriller with hints of romance splashed in

Both are very entertaining

OGURI SHUN a great Japanese actor is in both dramas. The thrilling part is the gap differences between the characters, plot, story line, and more. Please try it out and enjoy
