In Your Radiant Season Potential Plot

The plot follows how two different people are living through their own seasons. Sunwoo Chan is living his life like every day is summer with his upbeat personality and creative side, but he is hiding the painful memories from an accident that took away his hearing and left him suffering from amnesia for most of his life.

On the other hand, Song Ha-ran is in the middle of her own winter by isolating herself due to her past failures and wounds; even though she has been successful in the world of fashion.

Once Sunwoo Chan and Song Ha-ran have met again after seven years apart, they begin to slowly uncover all the hidden truths, lost connections, and shortfalls that had created all of the pain from their previous relationship with one another. Their emotional bond grows stronger with each day they are together, as secrets begin to reveal themselves, and their relationship transitions into a more romantic one, with a lot of mystery surrounding Sunwoo Chan’s accident and a lot of emotional growth for both characters. The romance grows slowly, while providing emotional healing arcs for both characters, as well as a mystery surrounding Sunwoo Chan’s accident, with an emphasis on character-driven storytelling rather than melodramatic storytelling.
