Han Chae Young, a prominent name in K-dramas, has achieved success with “Raising His Mistress’s Child,” a Korean-language adaptation of a globally popular microdrama that has generated over $15 million in revenue.
The series debuted on July 10 on the mobile-centric platform FlareFlow and has already amassed over 10 million views.
The original “Raising His Mistress’s Child” attracted around 4.8 million viewers and recorded more than 513,700 completed views. These impressive numbers led COL Group’s international platform to create a version specifically for Korean audiences.
The storyline follows a woman who survives a challenging childbirth, only to discover that the child she holds belongs to her husband’s mistress, while her own baby has been taken. Determined, she embarks on a journey to reclaim her child and seek justice.
The Korean adaptation has shown strong early engagement metrics, with an 84.4% retention rate for the first episode and 67.6% for the second.
Han Chae Young, renowned for her roles in “Boys Over Flowers” and “Autumn in My Heart,” exemplifies a regional trend where established film and TV actors are transitioning to mobile-first productions, as the microdrama format continues to attract larger audiences and increased production funding.
Timothy Oh, general manager of COL Group International and chief marketing officer at FlareFlow, commented: “Microdrama has evolved far beyond short-form entertainment. Today, audiences expect premium storytelling, cinematic production quality and performances from actors they know and love. Han Chae Young’s decision to headline the Korean version of ‘Raising His Mistress’s Child’ reflects how far the industry has come. Mainstream television stars increasingly recognize microdramas as a premium storytelling format capable of reaching millions of deeply engaged viewers. This marks the beginning of a new era, where the biggest stories, the best talent, and the most compelling entertainment experiences are increasingly being created for the vertical screen.”
FlareFlow, having released approximately 5,200 series, operates in 14 languages and has 33 million registered users across more than 200 countries and regions. The Korean version of “Raising His Mistress’s Child” is part of a broader effort by the platform to localize content by combining successful global intellectual properties with well-known local talent.
