MBC’s Friday–Saturday drama "Your Radiant Season" weaves multiple romance threads that deepen viewer engagement. Centered on Lee Sung-kyung and Chae Jong-hyeop’s "Radiant Couple," the series also charts a sunset romance between Lee Mi-sook and Kang Seok-woo and maps relationships across generations involving Kwon Hyuk, Han Ji-hyun, Oh Ye-ju and Kim Tae-young—broadening its appeal. Below, we break down the key charms of the series’ lead, Chae Jong-hyeop.

Song Ha-ran (Lee Sung-kyung) and Sun Woo-chan (Chae Jong-hyeop) offer each other mutual rescue, slowly mending one another’s wounds. After Kang Hyuk-chan (Kwon Do-hyung) dies and Song Ha-ran falls into deep grief, Sun Woo-chan shows up and proposes a three-month trial as a "neighborhood friend" to coax a smile back onto her face and keep their connection alive.
Sun Woo-chan conceals that he once spoke to Song Ha-ran on Kang Hyuk-chan’s behalf, a secret that adds a subtle tension to their growing relationship. Still, his steady kindness over the past seven years gives Song Ha-ran moments of bittersweet exhilaration. His bright, free-spirited energy—he lives each day like an endless summer break—gradually thaws the winter that has held her.
But after their reunion, Sun Woo-chan’s memory begins to falter and the situation quickly changes. Fragmented recollections that had surfaced sporadically start to connect, and the aftereffects of a past explosion deepen the cracks in his inner world. Cha Soo-jin (Lee Joo-yeon), who knows about the blanks in his memory, appears and corners Sun Woo-chan further. When Song Ha-ran faces Cha Soo-jin, the past Sun Woo-chan has been hiding reaches a point where it can no longer stay buried. With the truth behind his sunny facade creeping into view, viewers are left wondering how the three of them will navigate what comes next.
Episode 10 of "Your Radiant Season" airs on the 27th at 9:50 p.m.
