Doubt follows Jang Tae Su (Han Seok Kyu), the nation’s top profiler, who comes to know about his daughter’s secret intertwined with a murder case he’s investigating.
Military Prosecutor Doberman actress Oh Yeon Soo plays Yun Ji Su, Jang Tae Su’s ex-wife and Ha Bin’s mother. Ji Su stands at the heart of the father-daughter storyline, playing a key role in amplifying the mystery. As the shattered family’s story slowly unravels, the production team promises viewers shocking twists.
In the stills, Ji Su looks at her husband Tae Su with eyes full of resentment and reproach and is seen desperately embracing her young daughter Ha Bin. Additionally, Jang Tae Su and Yun Ji Su are a couple whose lives were torn apart by a tragic event in the past.
Oh Yeon Su shared, “I worked with Han Seok Kyu in Sons and Daughters, but we didn’t have many scenes together. When I heard he was joining this project, I was thrilled at the thought of working with him again, and I was both happy and surprised to be reunited with him in the role of a married couple.”
Oh Yeon Su also revealed why she decided to join the project: “The script itself was captivating. Each episode made me curious about what would happen next. Most of all, after meeting with director Song Yeon Hwa, I felt confident about the project.” She added, “Ji Su harbors a secret, and her hidden story is intricately woven. Viewers will feel the script’s meticulousness and complexity when they watch. It’s a good show and I’m looking forward to seeing it myself.”
