Unforgettable

“I will carry you forever.”

During a live music radio show, a letter arrives that was written twenty-three years ago. Through it we meet five friends, among them Beom-sil (Doh Kyung-soo) and Soo-ok (Kim So-hyun), and the first love that tied them together. Lee Eun-hee builds the story on that old letter, and Beom-sil carries the weight of what he never got to say.
