The 2025 MBC Drama Awards were filled with unforgettable moments, but perhaps nothing captured the audience’s heart quite like the surprise reveal of the first teaser for “In Your Radiant Season.” This upcoming romance drama has been making waves since its casting announcement, and the sneak peek confirms that we are in for an emotional, visually stunning journey when it premieres in the first half of 2026.
Pairing the charismatic Lee Sung Kyung with the “rising king of romance” Chae Jong Hyeop, the series promises a delicate blend of professional ambition, deep-seated mystery, and the kind of healing love that only comes once in a lifetime.
A Tale of Two Guarded Hearts
At the center of “In Your Radiant Season” are two individuals who have mastered the art of hiding their pain behind professional success.
Lee Sung Kyung stars as Song Ha Ran, the visionary head designer at the prestigious fashion house Nana Atelier. To the outside world, Ha Ran is the epitome of perfection—sharp, stylish, and composed. However, beneath the high-fashion exterior lies a woman who has intentionally isolated herself. Having endured the devastating loss of loved ones, she has built high walls around her heart, choosing the cold comfort of solitude over the risk of being hurt again.
Opposite her is Chae Jong Hyeop as Sunwoo Chan, a talented character designer at a world-renowned animation studio. Unlike Ha Ran, Chan’s defense mechanism is a bright, infectious cheerfulness. He is the person who lights up a room, yet he carries a heavy burden: a deep psychological wound stemming from a mysterious accident in his past. While he spends his days creating vibrant characters for others to enjoy, his own story is shadowed by a secret he isn’t ready to face.
Seven Years and a Summer Mystery
The newly released teaser sets a hauntingly beautiful tone. It opens with fragmented, atmospheric glimpses of Sunwoo Chan’s past—hints of a mysterious event that changed everything. The timeline then shifts to the present, where Chan catches sight of a crying Ha Ran. The contrast between her public persona and this moment of raw vulnerability is striking.
The teaser’s dialogue adds layers of intrigue. We hear a woman’s voice ask, “Summer of seven years ago?” followed by a man questioning, “Didn’t something happen to that kid?” These lines suggest that the tragedy haunting both protagonists might be interconnected in ways they don’t yet realize.
The emotional core of the teaser is revealed through poignant captions that hint at a long-awaited reunion:
“The girl who was like a spring breeze seven years ago showed up in front of my eyes again.”
This “spring breeze” metaphor suggests that Ha Ran was once a source of light for Chan, making their current roles—her as the isolated designer and him as the wounded optimist—all the more heartbreaking.
Why We’re Excited for “In Your Radiant Season”
What makes “In Your Radiant Season” stand out is its focus on “healing romance.” Rather than a simple love story, the drama explores how two people can help each other confront the “seasons” of their lives—the winters of grief and the springs of new beginnings.
-
The Chemistry: Lee Sung Kyung’s ability to portray complex, high-achieving women paired with Chae Jong Hyeop’s signature “warm-hearted” energy creates a dynamic that fans are already calling “the visual couple of 2026.”
-
The Mystery: The “unimaginable secret” mentioned in the synopsis suggests that the plot will have more stakes than a typical slice-of-life drama.
-
The Aesthetic: With Nana Atelier and a world-class animation studio as backdrops, the production design promises to be a feast for the eyes.
As their lives begin to intertwine, cracks start to form in Ha Ran’s rigid structure, and Chan finds himself pushed toward a new, terrifying, yet necessary chapter of his life.
“In Your Radiant Season” is set to air in early 2026 on MBC. Stay tuned for more updates as we get closer to the premiere!
