Petty Lies

Sulmi Bak’s Petty Lies presents a tense narrative centered on Mira, a tutor with a hidden agenda. She enters the home of wealthy single mother Jiwon to teach Yuchan, the boy she blames for her family’s death. The story unfolds within the sprawling estate, where Mira’s initial certainty about Yuchan’s cruelty begins to fracture. As she investigates further, she realizes the boy is not the true architect of the past harm. Instead, someone else in the household is manipulating events with a deviant plan that remains obscure until the end. Bak constructs a psychological thriller that relies on unreliable narration and domestic suspense. The plot draws on traditions of gothic fiction where the home itself becomes a site of dread. Mira’s internal conflict drives the narrative forward, contrasting her desire for vengeance with the complex reality of Jiwon’s motherhood. The book suits readers who enjoy slow-burn psychological horror and stories about fractured families. It may not appeal to those seeking fast-paced action or clear moral resolutions. The tension builds through Mira’s observations of the household dynamics rather than external threats. Bak qualifies this work through her focus on intimate, personal vengeance. The narrative structure follows Mira’s infiltration of the family unit. Each chapter peels back a layer of deception, revealing that the cruelty she seeks to punish is more complex than she imagined. The story does not offer easy answers but instead leaves the reader with the unsettling realization that the truth is hidden in plain sight within the domestic sphere.
