Both take place in a historical setting, are sapphic in nature, and the same actresses are the main leads.

Same lead actresses in both. Both take place in a historical setting, and they're sapphic in nature.

As soon as I watched the second episode of tracer, I sensed the similarities
Both male leads have unique jobs, in tracer it’s the tax service and in Vincenzo it’s as a mafia consigliere
In both dramas the male leads are committing just acts in order to achieve their ultimate goal of revenge, and in both this is carried out of carefully and strategically.
They are both refreshing with dark undertones (in my book at least), and I honestly believe that if you like one, you’ll like the other.

-Revenge
-Broken, purpose driven lead. Everything else in life is just noise to them
-Connection with law enforcement through their father
-Use them to pursue their goal but not necessarily allies
-To kill a monster you have to be one

The ML is a strong fighter who is sent to spy on the FL. The ML goes undercover to get close to the FL in a role where he is under the FL's authority. When the FL issues commands, the ML generally obeys and plays the role of a subordinate. The ML also becomes the FL's protector and saves the FL from harm on several occasions, even when it means risking his own life. And the ML does not let injury or illness get in the way of... intimacy.

One further parallel that is minor but amusing: the man who at first seems to be the ML's main romantic rival is later shown to have more romantic interest in a family member of the FL.

The FLs both come from rich and powerful families. They have built reputations for being cold, demanding, and prone to shallow flings. The MLs are both good looking and good fighters, and the FL makes it clear that she finds the ML attractive early on. The leads seemingly start out on different sides and the ML does not tell the FL about his connections to the most powerful people on his side. But the ML takes on the role of the FL's bodyguard and goes to extreme lengths to protect her from harm - even if it means risking injury or death. The ML falls for the FL quickly and has no problem with the FL's demanding personality (in fact, it seems to be one of the things he likes about her).

Both dramas are Chinese historical romances where the FL is a clever, strategic, beautiful and graceful princess who has to lie to everyone (including the ML) for a good reason.

In both dramas, the ML is strong fighter who falls for the FL quickly, respects her, and always defends / protects her - even if it means risking his own life.

And in both dramas the FL does not know that the ML is connected to the emperor and distances herself from the ML when she finds out.

But there are two major differences: ZGZZS is short and fast and (for lack of a better word) just plain horny. The Princess Wei Young is long with lots of characters, subplots, and repetitive themes and the leads have very limited skinship. They're both great dramas in their own way.

they both are the best crime dramas ive ever watched. both leave you on edge. both have a burning romance. and theyre both my fav shows ever. HIGHLY recommend vincenzo if you liked flower of evil.

* Three part drama (ML, ML-with-amnesia, ML-recovers memories)
* In both, FL falls for ML early
* In Be my princess (part 1) ML falls for FL; in Prince-Frog (part 1) ML hates FL
* In both (part 2 and part 3) ML falls for FL
* normal-ML is cold and warms up
* In both (part 3) 2FL lies to ML about FL

Same wuxia genre and a nicely thought-out plot progression where the resolution of one mystery/arc opens up the next mystery/problem to be solved arc. Suspense keeps driving the plot forward, but neither drama is overly intense.
Both have playful but intelligent male leads.
Romance is sweet but understated.
Be warned, JOL only resolves partially as a Season 2 was planned; LOF has a nice satisfying ending.

these two show are siblings! They start the same storyline, our police boy suspects other one about murder someone etc. Both show is bl/bromance with dark scent (Beyond evil is darkest of course)

maybe not story but the vibe is similar, ther are two male main characters which fights for the justice, and only one of them is police. One character looks like carefree and other one is little serious. Both show is bl/bromance with comedy + dark scents also

story is similar, two male characters fights for the justice. Two of the characters in the shows are different kinds of nature and humour. Both show is bl/bromance with comedy + dark scents

These two plots are veryyy similar
Both the male leads loses their memories each day and the female leads has to get the male leads to remember them each time.

Has the two male lovers going for the female protagonist.
Both have great storylines and both set back to the Chinese dynasties.
