If u like republic spy drama or spy dramas in general then both drama are worthy watches. A cleaver protagonist and powerful antagonists with twists and turns.

Watching this reminded of two dramas one of them is signal, both are about seriel murderer during early times when technology wasn't advanced and it was different finding the evidence

Numbers really reminded me of suits the whole under dog male lead concept becoming the smartest and the mentor mentee realtionship with his senior accountant

These two sounds so similar in terms of plot settings except for the line of work both deal with smart male leads who want to fight against workplace corruption and a whole lot of related consequences

Both the shows have following
Smart male lead
Insider investigation
Corruption
Politics
Wanting justice

Both shows are based on ghost seeing leads and exorcism although the character may differ but the foundation of premise looks pretty similar

If you likes one you'll definitely enjoy the other both revolve around a trio of two guys and a girl and how their relationship goes through a change over time for better or for worst

If u enjoyed one you'll love the other both have ml that are surrounded by people that seems life threatening and focuses on their unrealiable narrative and psych
