Hello Monster (2015)

They are both crime dramas with a past connection between the male lead and the female lead. Throughout the drama, the crimes they solve lead to a bigger picture which shows their past connection. Also a romance develops between them in both dramas.

Both shows:
> Have a ML who's trying to unravel a mystery involving them and their loved ones.
> The leads reluctantly start working together, but then they grow to care and rely on each other.
> The FLs are agents (one is a detective, the other a NIS agent).
> FLs are one of the few who believe in the ML.
> The show is action-oriented with a side of romance.
> Who the "big baddies" are is predictable.
> There are a bunch of mini antagonists along the way.
> Corruption is rampant.
> Have a group of misfits banding together to stop the big bads.

Both:
- deal with criminal cases
- have a mystery that you want to solve
- have great plot twists
-have the romance (in ' I Remember You' it's more of a secondary plot, whereas 'He is Psychometric' focus onto it)
-the main couple has something in common since childhood but doesn't know/talk about it at the beginning
- have awsome bro-romance, 'family' relations and brotherhood problems
- have well-developed psychology and depth of the character
- and make you feel like Sherlock x

I recommend this both drama because , Male lead and Female lead
try to solve problem
In one drama explosion and another student murder/suicide

Same scriptwriter and same tendency to relativity of good and evil.

Both have criminal psychologists/profilers as main leads
In both shows, the main leads solve different crimes, each of which offers more clues to a deeper conspiracy'
In both shows the main leads are trying to find the truth about a crime in the past that personally affected them

Both dramas depicts dark family ties with psychopaths. Both murderer believe, that hero (policeman/detective) are like them.

"Hello Monster" and "Strangers from Hell" have different plots, but their concept is similar about psychopaths who are entangled with each other. The main psychopaths are influencing and manipulating their victims by using mind tricks to follow their path, whether it's the same or different outcomes.

The story unfolds really nice and slowly. One step after another. There are many surprises during the drama, but they are solved slowly, step by step. Also, great character developing and acting. Be sure to have tissues right next to you.

-Male lead and smart female lead.
-Both have romance but it is much less in Subete ga F ni Naru
-They both are solving murder cases.
-Both have deep and dark plot.

Both have intrigue, uncoverin old dark secrets, crime drama and homoerotic subtext. There's also one or several characters suspected to be sociopaths.
Basically Beyond Evil, The Devil Judge and Hello Monster are the holy trinity of this kind of genre.

Similarities:

The main leads fall in love (though Hello Monster has less romance I believe and they don’t get together until the very end)
More serious male lead in both
Smart female lead in both
Different cases get worked on but there is also one main big case leading up through the series
The chemistry is better for the main leads in WASFIL I believe.
Both are very enjoyable to watch ?

the same ML playing the role of a criminal investigator... the both characters have some hidden past behind them. you can try this drama too... it's pretty good and we have police FL'S in both the dramas

Both have this suspense feeling and the past/present thing (main characters knew each other in the past) aaand in both dramas are handsome guys!

Both dramas give rise to the question of good and evil in humans and whether that is something out of our control or not. Bloody Monday have a genius hacker with the japanese special forces at its center, looking for his dad (and the mystery of his disappearance) while fighting against a group of terrorist wanting to "reset" the humanity. I remember you focuses on a genius consulting detective wanting to solve the forgotten mystery of his rather unfortunate past, while looking for his missing brother and along the way solving various crimes & clues that bring him closer to the core of the human psyche and the hazy gray zone of what is right and what is wrong. Both dramas are full of suspense as well as various plot twists.
