Both offer a fun, exaggerated take on modern romance, using dramatic tropes to create a compelling, often hilarious, path to love.
Both K-dramas use a murder as the catalyst for exploring themes of female agency, systemic failure and injustice, and the desperate measures women resort to when they feel the world has abandoned them.
In both series, the central mystery isn't a typical generic crime but a personal case that fractured the protagonist's life. For 'Nine Puzzles,' it's the unsolved murder of her uncle; for 'The Price of Confession,' it's her husband's murder and the subsequent legal and moral fallout.
Both dramas are similar in that they are both dark, interconnected crime thrillers that explore the high cost and moral fallout of a murder and the subsequent desperate actions of the people involved.
Both dramas rely heavily on the "fake relationship" or "fake identity" trope within a workplace romantic comedy setting to drive the main plot and explore the growing feelings between the leads, dealing with many hilarious misunderstandings along the way.
Both dramas centre around maneuvering through the awkward teen years with lots of humour sprinkled in, including dealing with self-image issues, crushes, family drama and unintentional (and often hilarious) self-sabotage.
