- Focuses on chasing after a serial killer
- Both are investigation dramas with comedy in them. Although, Inspector Koo had more of a dark-humoured vibe than your usual comedy dramas.
- Honestly, they just give me the same vibes

- Both female leads are being punished in the same way for committing a sin in the past
- Both dramas include the plot of customers being offered magical dishes to help fix their problems in life
- Both female leads have sidekicks helping them out.

Although KG focuses on more of a 'game' category and 35SNK on more of a 35 year old rejoining high school as a student to deal with the modern day problems, they both still revolve around teachers trying to deal with said problems.

— Both dramas centre around a cult
— Both dramas centre around corruption and dark secrets
— Both dramas include students as the main characters ( well Nobody Know’s main character is a female detective but a high school student is apart of the main cast. It revolves around the high school student falling into despair.
— Both dramas start off hopeless, you feel like nobody’s going to save them. You’ll feel aggravated at some of the characters, though Save Me considerably has more twisted and insane characters

They are not that similar but not that far of either. Anyway, both dramas are amazing imo
