The upcoming drama “In Your Radiant Season” follows the story of Sunwoo Chan, a man who approaches each day as if it were an exciting summer vacation, and Song Ha Ran, a woman who has closed herself off from the world, living as though her life were trapped in winter. Through this contrast, the series explores emotional recovery and personal change.

Lee Sung Kyung, Han Ji Hyeon, and Oh Ye Ju portray the three sisters of the Nana Family, characters who share the same emotional scars but have learned to endure life in different ways. Their relationship forms a central emotional foundation of the drama.
Lee Sung Kyung takes on the role of Song Ha Ran, the eldest sister and head designer at Nana Atelier, one of South Korea’s leading high-end fashion houses. As the pillar of the family, she maintains balance between her grandmother Kim Nana and her younger sisters. Despite her flawless public image, Ha Ran withdraws from the world after losing loved ones, suppressing her emotions by immersing herself in work as she attempts to rebuild a life that was abruptly shattered. Her quiet endurance and sense of responsibility are expected to leave a strong impression on viewers.

Speaking about the sisters’ on-screen chemistry, Lee Sung Kyung praised Han Ji Hyeon for portraying Ha Young with such natural charm that it becomes difficult to distinguish acting from reality. She also shared that Oh Ye Ju’s portrayal of Ha Dam naturally draws affection, adding that the three sisters come together with a harmonious balance, each offering a distinct presence.
Han Ji Hyeon plays Song Ha Young, the second sister and a junior designer on Design Team 1 at Nana Atelier. Cheerful and playful, she serves as a bright force within the household, easing the emotional weight carried by the family. While she appears optimistic on the surface, she is the most honest about her feelings when with her family, adding emotional depth to the sisters’ dynamic. Han Ji Hyeon described the filming set as having a genuinely family-like atmosphere, where laughter flows easily and emotional scenes unfold with natural focus.

Oh Ye Ju portrays the youngest sister, Song Ha Dam. Outwardly, she seems the most composed and independent, excelling academically and managing everything on her own. This strength, however, is her way of protecting herself from being seen as vulnerable. When the usually dependable Ha Dam enters her first phase of rebellion, it becomes a turning point that challenges the sisters’ long-standing bond and signals significant change.
Oh Ye Ju shared that filming at Nana House often feels like being at home, noting that she feels well cared for by her co-stars. This sense of comfort and trust, she explained, contributes to the warm atmosphere that defines their scenes together.
“In Your Radiant Season” is scheduled to premiere on February 20 at 9:50 p.m. KST.
