Secretly steaming open envelopes and reading the letters inside, Bilodo has found an escape from his lonely and routine life as a postman. When one day he comes across a mysterious letter containing a single haiku, he finds himself avidly caught up in the relationship between a long-distance couple who write to each other using only beautiful poetry. He feasts on their words, vicariously living a life for which he longs. But it will only be a matter of time before his world comes crashing down around him.
