Vincenzo

Well, definitelly MSM is a more lighthearted drama, HOWEVER, both dramas have mobster main leads and have also incorporated humor in their plot.
Sooo if you are in the mood for such a drama,you should check it out. I will put more details when it ends as I will be able to compaire and contrast

Just if you want a serie version because i think it's exactly the same story like EXACTLY (i didn't see quantic physics yet)

Here are some similarities between the male leads, female leads and the shows.

Male Leads
- Smart & Calculative
- Skilled in their area of expertise (mafia & doctor)
- Seek revenge
- Trying to get rid of corruption
- Fights injustice with injustice
- Both are intimidating & induces fear upon their targets

Female Leads
- One is a lawyer the other a psychiatrist
- Both teamed up with ML's with a shared goal

Show
- They both have very similar vibes
- Have similar tags: suspense, law, crime, revenge, smart male lead, corruption etc.

If I wasn't able to convince you to watch it, just give the first episode a try and you won't be able to stop :P

Both are funny and have an action in them. It is a thriller type. The male lead is the same.
After a long time, the hero is back. If you want to check out Song Joong Ki performance in another work before watching Vincenzo, please consider checking this drama.

The mix of humor and seriousness is very similar! Both of the series have protagonists that take justice into their own hands. They also work as a team.

The tones of the show are similar. It’s part thriller and part comedy. They both have themes of revenge and found family. Both dramas are so much fun. Highly recommend both.

Both have a lovable and comedic mishmash of store workers (TKSL)/store owners (Vincenzo) who come to rally around the main character and aid them in their missions. Pieces of found family can be found here and there. Vincenzo is a bit more serious and more overt in found family. Romance is treated more as a side troupe than the main focus in both.

Man to Man is more lightweight than Vincenzo. Either way, the action scenes both dramas have is fire. They both show their soft side to the people they love but seem cold to others and make calculated decisions before anything happens. Until the day they mess with the woman they love, of course. That day they go berserk and make emotional decisions.
Vincenzo is darker with an anti-hero theme. I am not sure if the recommendation would live up to the expectation the other way around: from Vincenzo to Man to Man.
If you enjoyed espionage and strong male leads who don't go suddenly good-for-the-girl cliche, Vincenzo is a good follow-up.

Vincenzo is real mafia but he is meddlesome people working for law. People around him are puzzled by this association. Plot is intriguing and partnering and alliances are necessary to progress. Finesse and elegance.

The thriller aspect and the main leads' dynamics are similar in both dramas. Even though both dramas have complete different plots, if you liked one you'll like the other for sure. Both stories revolve around the male protagonist who is trying to take "revenge" and in the process, meets people that help him.

So far, Vincenzo has more romantic moments between the leads whereas Mad Dog didn't have a explicit romantic line but the sexual chemistry between the leads were to DIE FOR.

P.S Mad dog is truly a fantastic drama I suggest everyone to try. It's an all-time underrated gem

Both are involved in justice system. Court setting. Several young lawyers. Good vs evil. Criminal and social justice.

Similar vibes and characters. Made by some of the same people and it has a cameo form the main actor form Vincenzo

-both dramas revolve around mafia
-both females have unique characters
-both males are charming and powerful in a manner
-both dramas have romance and comedy

Both shows feature a group of eccentric characters who fight for justice in their own unique way. The leads are both lawyers who end up working together against a common enemy.

Vincenzo (2021) and Breaking and Re-Entering (2024) are two thrilling titles that explore the world of crime and justice but with their unique twists. Vincenzo follows a Korean-Italian mafia consigliere who returns to Korea and uses his criminal skills to fight corruption, blending dark comedy with intense action. Meanwhile, Breaking and Re-Entering explores characters navigating the criminal underworld, likely with its blend of suspense and humour.

Both shows explore morally complex characters and offer thrilling plots filled with clever schemes, unexpected alliances, and moral dilemmas. I have to say, I highly recommend Vincenzo (2021). It's an absolute rollercoaster ride that combines sharp wit, intense drama, and some truly unforgettable characters. The way it balances its darker elements with moments of levity is truly masterful, making it a standout in the crime drama genre.
