Similar characters. We have an older, more cynical and serious character that does not hold back to fight for his justice, while the younger one is trying to fight for the "good" of humanity. Both revolve around the law and both evolve around similar concepts. Generally both dramas give off very similar vibes.
In both series, the interaction between a younger and older man in the field of justice is the central theme( auditors in one series, attorneys in the other). Both operate in an ill-designed system where defeating criminals requires cunning—and maybe more than that. The elder is an expert in his profession, but his techniques and his demeanor is more hard and cynical, while the younger ml has a "good and pure" heart but is a naive while being intelligent as well. The two's interaction alters and tests them. Both dramas give off very similar vibes
This drama also has a similar premise of an experienced audit manager mentoring the newbie or inexperienced junior auditor. Instead of legal cases, the drama tackled audit cases about the company corruption. The male lead is strong and principled like the FL in Good partner, but the newbies give them a bit of the human touch.
