In Your Radiant Season: Lee Sung Kyung and Chae Jong Hyeop Reunite in MBC’s New Fantasy Romance Drama

MBC is preparing to unveil its highly anticipated new Friday-Saturday drama In Your Radiant Season, which will premiere on February 20 at 9:50 PM. The series has already captured attention with the release of its second teaser video, highlighting the evolving relationship between Lee Sung Kyung and Chae Jong Hyeop.

In Your Radiant Season (planned by Namgoong Sung Woo, written by Jo Sung Hee, directed by Jung Sang Hee and Kim Young Jae, produced by Pan Entertainment) tells the story of two contrasting characters whose lives collide in unexpected ways. Sun Woo Chan, a man who lives each day as if it were an endless summer vacation, meets Song Ha Ran, a woman who has locked herself away in the coldness of winter. Their encounter sets the stage for a romance that defies prediction, awakening frozen time and bringing warmth to places long untouched.

The newly released teaser video, unveiled on February 4, portrays the poignant reunion of Song Ha Ran (played by Lee Sung Kyung) and Sun Woo Chan (played by Chae Jong Hyeop), who meet again after seven years. The teaser centers on their professional collaboration, with Ha Ran working as a senior designer and Chan as an animator. Their fateful partnership becomes the backdrop for a gradual transformation in their relationship.

In the teaser, Ha Ran struggles to conceal her unease as Chan approaches her with openness and sincerity. Determined to maintain boundaries, she insists, “I do not want to create variables,” drawing a clear line between them. Yet Chan remains close, gently narrowing the distance with his natural charm. This contrast—Ha Ran’s guarded demeanor against Chan’s carefree persistence—underscores the tension and chemistry between the two characters.

Chan’s candid words, “I wanted to let you know there is a way. I have also stood alone in the middle of winter,” reveal his heartfelt sincerity and hint at the emotional scars he carries. The teaser interweaves fragments of Chan’s past, including a mysterious accident that forced him to endure a harsh winter of solitude. These glimpses add depth to his character, showing that his bright exterior conceals hidden pain.

One of the teaser’s most memorable moments comes when Chan proposes a “three-month trial as neighborhood friends,” a lighthearted suggestion that reflects his playful personality. This invitation not only adds a spark of excitement but also begins to thaw Ha Ran’s frozen heart. Her subtle changes, from hesitation to curiosity, raise anticipation about how far their relationship will progress. The teaser closes with Ha Ran’s quiet yet impactful line, “Is that still valid?”—a statement that signals the slow but undeniable movement of her once-stalled season and foreshadows the beginning of their radiant romance.

With its blend of emotional storytelling, character-driven drama, and a touch of fantasy, In Your Radiant Season promises to deliver a refreshing take on romance. The chemistry between Lee Sung Kyung and Chae Jong Hyeop, coupled with the drama’s unique seasonal metaphor, positions the series as one of the most intriguing new releases of 2026.

Audiences can look forward to the premiere of In Your Radiant Season on MBC, airing February 20 at 9:50 PM, where the journey of Chan and Ha Ran will unfold in full.
