Core premise:
To investigate her sister’s “accidental” death, the genius criminal profiler heroine disguises herself as a sweet, innocent girl and marries the corporate CEO who is her prime suspect. She thinks she’s putting on an act, unaware that she is actually the male lead’s “pawn,” meant to draw out the mastermind while he keeps her under his protection. Two clever people hiding behind masks probe each other’s true feelings amid a web of lies, until an adorable little boy who looks just like the male lead shows up at their door with a DNA report, throwing their dangerous game of chess into chaos.
