## Synopsis

My Secret, Terrius (2018) is a South Korean conspiracy thriller series created by Kang Dae-sun for MBC. Across one 32-episode season, it follows Go Ae-Rin (Jung In-sun), a widowed single mother whose quiet life is upended after her husband's death, and Kim Bon (So Ji-sub), an NIS intelligence agent living next door who becomes her unlikely ally. Together they dig into the truth behind her husband's entanglement in a sprawling conspiracy, and each episode peels back another layer of hidden loyalties, covert operations and buried family history. The engine is simple and propulsive: a grieving woman who wants answers, a secret agent who must protect his cover, and powerful people who would rather the truth stay buried. Principal supporting roles include Son Ho-jun, Im Se-mi and Seo Yi-sook. The show mixes the emotional texture of a Korean domestic drama with the tension of a spy thriller, producing a register that is melancholic, tense and quietly hopeful. Fans of Vincenzo, Signal and Big will find resonance in its blend of intrigue, personal grief and secret identity. Its single completed season makes it a contained, binge-friendly watch.
