Rakuten Viki is expanding its Korean drama lineup with A Bona Fide Killer, a suspense-driven series that combines high-stakes action, family drama, and mystery.
Premiering exclusively in Southeast Asia on July 31, the series follows an ordinary working mother who secretly leads a double life as one of the world’s most feared assassins.
Based on the popular Kakao webtoon, which has accumulated 180 million views, A Bona Fide Killer centers on Yoo Bo-na (Kong Hyo Jin), a devoted wife and mother whose seemingly ordinary life conceals a dangerous secret.
Bo-na lives with her husband, newspaper reporter Kwon Tae-seong (Jung Jun Won), and their young daughter. Unknown to them, she is actually “Kingfisher,” a legendary sniper working for a covert organization tasked with eliminating some of the world’s most dangerous criminals.
After taking a three-year maternity leave, Bo-na returns to the field, forcing her to navigate the demands of motherhood and marriage alongside high-risk assassination missions. Her carefully protected identity faces its biggest threat when Tae-seong is assigned to investigate the mysterious killer known as Kingfisher.
The series explores the collision between extraordinary responsibilities and everyday family life, using Bo-na’s secret identity to examine marriage, parenthood, survival, and the lengths one will go to protect loved ones.
