Joy loves her job at the post office and delivering letters every day. She was assigned to dispose of the unsent letters until she read an unsent letter for Wendy. 

She thought the letter was beautiful to be thrown out and so she put it aside as she started to read another letter. Letters after letters some of them are heartwarming and touching stories, she felt various emotions, and curiosity hit her and she wondered why these letters didn’t reach their destination. 

Every letter deserves to be delivered, every feeling deserves to be felt. So Joy decided to deliver the unsent letters and who would know Wendy would join her journey.
