Description
Mira is a desperate young woman, hired by a wealthy single mother to tutor her lonesome son, Yuchan. But Mira is not who she presents herself to be; she is haunted by the death of her own family and motivated by the dark pulse of vengeance. Yuchan was cruel to Mira’s mother. A kind of cruelty she can’t ever forgive.
And then there is Jiwon, the boy’s mother, a bad mother, Mira thinks—or so Jiwon tells herself she must not be.
But as Mira spends more time in the family’s sprawling home, she begins to suspect Yuchan is not the culprit she’s after. Someone else in the family has been pulling the strings. Someone with a deviant plan she can’t begin to imagine.
Structured around four different letters and journal entries: Mira's, Jiwon's reply, Yuchan's younger brother's diary entry and, finally, Mira's own written recollection. Each new section brings us deeper into a web of cruelty, consequence, and closer to the truth.

A quiet scream of a novel.
Petty Lies is a slow-burning descent into obsession told through a patchwork of confessions, accusations, and half-truths. What begins as a seemingly straightforward story of a live-in tutor in a wealthy household quickly unravels into something much more unsettling.
Mira arrives carrying grief like a second skin, determined to right a wrong she believes has been committed against her family. But as her perspective gives way to others—each with their own fractured logic—we begin to question everything. No one here is innocent, and yet no one is fully to blame. That gray space is where Sulmi Bak works her magic.
The story unfolds through letters and journal entries, four sections, each voice pulling you deeper into a psychological maze. The writing relays a creeping dread. What impressed me most is how the novel resists clean answers. It doesn't just tell a story it pulls you straight in!
Trigger warning - There is animal violence discussed.
