The upcoming drama “In Your Radiant Season” has released new official posters, highlighting a reunion that takes place seven years after the leads first crossed paths. The series follows Sunwoo Chan (played by Chae Jong Hyeop), a man who lives each day as if it were a carefree summer vacation, and Song Ha Ran (played by Lee Sung Kyung), a woman who has closed herself off as though trapped in a long winter.

The newly revealed posters focus on the connection between the two characters, which began with a brief encounter on Jamsu Bridge seven years earlier. One poster, divided into upper and lower sections, depicts that fleeting moment amid a crowd. Song Ha Ran stands silently, lost in thought, while Sunwoo Chan looks toward her, leaving behind a quiet but lasting impression.
Another set of posters shifts to the present day, capturing their reunion after seven years. Now meeting again as chief designer Song Ha Ran and animator Sunwoo Chan, the pair draws attention simply through their first exchange of greetings, conveying a noticeably brighter and more open energy than before.

According to the production team, although their connection began years ago, the seasons of their lives have unfolded in completely different directions. The drama will explore whether the hidden story behind their reunion, along with fragmented memories from the past, can ultimately come together to form a single, shared spring.
“In Your Radiant Season” is scheduled to premiere on February 20 at 9:50 p.m. KST.
