The Light in the Night (2023)

It’s about psychological things, police investigation, crime investigation. Bromance, enemies to buddy’s. Novel adaption.

It's a bromance obv. And also this jitd give you massive heartbreak so you gotta cure it with some pure bromance ?

Both censored adaptation of same sex story
Both written by the same author Priest
Both have ml battling with childhood trauma and humanity
Both have happy go lucky ml who hides their pain

A cop team up with civilian who expert in psychology. Both of drama containing interesting cases with their own characteristics. Justice in the Dark has better chemistry on screen.

Together solving cases (murder, missing persons, etc). One cop with calm persona and tent to be more serious in his worklife while another one is a fun character but smart ass.

Both are adaptation of BL webnovel...both has suspense and mystery...Both are double male lead drama...

Both have the theme of some sort of 'Serial Killer Gene' (that in some cases is a 'Genius Gene'), and somewhat explore the ethics using that knowledge

Both are about solving crimes, though Mouse is more about a big overarching case, while Justice in the Dark seems to be broken up into smaller cases that are connected (once it's fully released, this might be different)

Mouse does not have any BL themes, and seems to be more graphic when showing crime scenes

WIK and JITD/Silent reading is written by Priest , so you can feel the same vibe (although this rec is based on the books).

There is the element of Mistery present in both darams.

JITD - Excellent camera work and you can feel the chemistry between the actors (although subtil)

Same author, similar themes.
Same kind of team work in law enforcement.
Both have a gritty urban atmosphere.
Both have a friendship/romance/bromance that tries to survive in a world full of inner and outer conflicts.
