A Piece of Paper

Ki-beom discovers a hidden note in his living room wall—a passage from a book that matches a memory from his past. Driven by nostalgia, he tracks down the previous tenant, only to find a complete stranger. During a chance encounter at a café, his infant son, On-yu, unwittingly drops the note into the stranger's book. That night, as the woman faces the crushing weight of a failed job interview, she finds the timeless words. Through this unexpected messenger, an anonymous message of hope finally finds its way to someone who truly needs it.
