Similar feeling, Thai BL romcom. One childish male lead who's in love with a celebrity and has an overbearing older brother. Ends up falling for another man.

They both have firefighting storylines, they perform exciting fire and rescue missions.The support leads are firefighters the same as bright eyes in the dark.
They both have people having internal conflicts in choosing between family and the firefighting career, i.e. they don't have time for family anymore.
Not getting support from their family in chasing their dreams is also common in both..

They both involve firefighters as the ML, has team friendship amongst the firefighter squadron. Both shows have scenarios where they get to save people and learn from their mistakes. This one has slight romance compared to bright eyes in the dark. If you enjoy firefighting story lines give this a try.

Both Concrete Utopia and The Flu are dystopian, desperation of disaster, humanity and bleakness of the world

The chemistry between the ML and FL is what these two dramas have in common. This is due to the actress, Zhang Jing Yi who never fails to connect with her costar.

I think their character rolls are same. One is a cold male lead and the other is playful male lead. It's store is not same but I think it's ok .
I think huzi and wei wuxian are same Playboy .

Comparable vibes.
Both are "spy novel" dramas where secrecy is key.
Secret organizations, check.
Brainwashed organization members, check.
FL leads are great fighters, check.

Also about public officers who oversee an outdoor jurisdiction. Jirisan had a whole mysterious backstory and isn’t about policing. There is also a lot of action, much more than in Han River Police.

About front line heroes who face action packed situations and solve crime. Also has some comedy and light hearted scenes as well as bromance and competition.
