N에 담긴
This pattern means that something is contained in, carried by, or expressed through something else. It often sounds literary and is especially common with feelings, memories, intentions, or meaning, not just physical contents. In the story, "편지에 담긴 긴 이야기" shows this figurative use. Example: "그 편지에는 오래된 그리움이 담겨 있었다."
그 편지에는 오래된 그리움이 담겨 있었다.
The letter contained 오래된 longing.
