Don Quixote (2011)

They have a similar feel to them, even in the theme song. They are both funny and have yakuza members doing things yakuza don't normally do. They both put you in a good mood.

Both involve a main character with a supernatural secret identity that is the opposite of their personality.

Both are super hilarious dramas that has Yakuza characters.

Both are hilarious dramas and both dramas have Yakuza characters.

Both dramas main leads gets their bodies switched with each other. That's all there is in common. Oh and both are amazing dramas. Don Quixote has a lot of good comedy and in some terms it's more realistic while Secret Garden concentrates on romance between main leads.

Although different in plot, these are both comedies that feature Matsuda Shota. If you liked his wacky and very funny character in Don Quixote you might be interested to watch more. He has a quirky character and great comedic timing in this drama as well.
