The Invisibles (2023)

Both has similar cast members and team dynamic. Some of the cases in I've got the power gets so dark I was surprised despite the upbeat mood and poster. The synopsis sounds worlds apart but it's not at the end of the day if you like the balance of action, mystery romance and friendship check them out

Both dramas share some of the same actors and actresses. Line Watchers is about the lives of HK Custom officers while the Invisibles is about HK Anti-terrorist officers and the Phantom Tactical unit.

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

Similar vibes. One is about airport and maintaining public and aviation security, while the Invisibles is about HK CTRU (Counter Terrorism Response Unit) and the POTT (Phantom Operation and Tactic Team) that solves high danger level cases.
