This lyrical documentary begins with a combination of images showcasing warm memories and the sound of waves. The film features a letter-like structure, delicately portraying a deep, affectionate longing for someone. S's letter is from the past, but by the director of K's letter, it reaches the audience simultaneously. This offers the viewers a condensed experience of a family's past and present, enabling them to imagine and connect with the family's life. The faces that have endured loss appear unexpectedly calm, yet this calmness leaves an emotional impact on the audience, lasting long after the film ends. (KANGYU Garam | Director)
