Hi, I'm looking for series with interesting/smart ML ;)
I don't really have many guidelines/expectations for the series, please tell me at least two sentences about the series you recommend (may contain spoilers :) I often search for the series I plan to see on tiktok because I prefer to know what to expect so as not to come across something that could hurt me), but:
+10% to my interest if FL is not unlike ML very stupid or annoying (I really liked the balance in Big Mouth)
+10% to my interest if it's BL or bromance (can also be a censored adaptation of a novel) or does not contain any pairings (as in Vincenzo)
+10 % if it's a finished series  
+10% if the series has light fantasy elements (can be like Alice on the borderline or Reborn Rich)

Thanks in advance for all recommendations :D 

From the dramas you mentioned ......vincenzo and big mouth..... I'd recommend you:
Devil Judge - judge decides the law needs to be changed to public judging.
Taxi Driver - group of people that take revenge on others
Beyond Evil -  two guys get paired up for a case but the younger one is especially suspicious of the older one and thinks he might be a murderer
Lawless Lawyer 
Evil Minds - a genius in criminal psychology collaborated with a police office to crack a series of bizarre campus murder cases,
Prison Playbook - guy ends up killing someone and being send to prison for that. his friend is a prison guard there.
60. Days Designated Survivor - something happens and the whole government representatives die apart from one man. He ends up being the representative for 60 days. its really really good
When the devil calls - story is based off on Goethe's Faust.
Good Detective - a duo ends up being partied together on the police but they are kinda suspicious of one another
King of Pigs - revenge drama
Under the Skin - talks about a profiler and a police man working together
Signal - korean drama. He is a young police officer that finds a walkie talkie and ends up connecting with someone 20 years in the past.
Money Flower - korean drama. revenge story . He is an employe and his role? Well speaking methaporically its like this: He is a puppeteer and everyone involved with him are his puppets.
Watcher - korean drama. kinda similar in that regards. we have a revenge story,
Gannibal - japanses drama. He is a police officer that moves with his family to a small village. And it turns out the village is anything but normal.
Gold Panning - Chinese drama. This one is difficult. You either love it or find it boring. The drama takes place in the late 80ties in china during a gold mining rush. It tells you about greed, obsession, murder. and life.


 Lady Lilith:
series with interesting/smart ML

 Lady Lilith:
finished series

 Lady Lilith:
light fantasy elements

 Lady Lilith:
FL is not unlike ML very stupid or annoying

 Lady Lilith:
BL or bromance (can also be a censored adaptation of a novel)

All of the dramas below are complete, have smart / interesting MLs, and include at least one of the other criteria you listed. See each drama's synopsis and tags in the linked drama page for more details.

  • Who Rules the World - Wuxia. Both leads are talented martial artists with hidden identities. The FL is not stupid or annoying.
  •  Sound of the Desert - Wuxia. To avoid spoilers about who the FL ends up with: one male lead is a talented businessman and self-taught doctor. The other male lead is a talented general. The FL has some basic martial arts skills plus other talents. I personally found her slightly annoying in one or two scenes in the first few episodes (where the writers emphasized her "raised by wolves" background), but otherwise she is smart, interesting and not annoying. 
  • The Untamed - Wuxia. Censored adaptation of a BL novel. The leads are talented disciples of prominent cultivator clans.
  • You Are My Glory - Modern rom com / life drama with no fantasy elements (except for scenes where the leads play a mobile game with fantasy characters). Although the FL is not a genius in academics or naturally gifted in gaming and athletics like the ML, she has her own set of talents and both leads are smart and not annoying, with high IQs and EQs. The ML faces some big life decisions and self doubts that make him more interesting than some other one-dimensional genius MLs.
  • W - Modern romance with sci-fi / fantasy elements (the FL enters the world of a comic book where the ML is the main character). The ML is a talented genius. The FL is a doctor. IMO the FL starts out a little bit annoying / has some not-super-smart moments, but she improves.
  • The Beauty Inside - Modern romance with sci-fi / fantasy elements (against her will, the FL's body regularly changes so that she looks exactly like various other people of all ages, races and genders). The ML is a competent businessman with prosopagnosia (face blindness) and the FL is a popular actress. Both are relatively smart and both are fairly direct and sometimes even abrasive, but not malicious or annoying.
  • Hello Monster - Modern crime drama with platonic bromance (biological brothers) and a bit of romance. The ML is a genius criminal profiler with a unique personality. The FL is a competent detective.
  • Fall In Love - Republican era romance drama. The FL is from a prominent business family. The ML is from a prominent military family. Both are fluent in several languages and very smart / competent.

Here are two Chinese dramas where I felt Ml and Fl were amazing. 

Love Me If You Dare (Cdrama) : Bo Jin Yan (Wallace Huo) as a Ml has this amazing charisma. He's intelligent, antisocial, plus a criminal psychologist. The Fl here is her assistant but not annoying. 

The Confidence (Cdrama) : Ml is an actual villain so he's strong and ruthless. Fl is also so strong. There's a cat and mouse chase between ml and fl. Tho there's only one side love from ml, no actual romance. But they've great chemistry.
