Both are directed by the same talented director (xin shuang); they are both modern crime thrillers that explore different social themes ie family dynamics, human behaviour, 'good' people making bad decisions, the impacts of those decisions etc. Both are superb productions that should be watched by more people!
Both dramas are directed by the same director and are short suspense dramas. The story also focuses on a trio but in The Long Season there are two trios that span two generations.
