A special delivery from a fourteen-year-old postman who connects hearts.
“Are you confused because I left so suddenly?
“I will convey the sincerity that I could not convey on your behalf!”

‘I should have talked to the friend I wanted to be close to first, I should have firmly refused things I didn’t like, I shouldn’t have gotten upset with my mom for no reason… …’ Every day, teenagers hesitate and regret the choices they are given, big and small.
This is especially true when it's a new semester or school year.
In an environment where they face unfamiliar classrooms, teachers they have never met before, and awkward new friends, teenagers sometimes even lose touch with their relationships.
The same goes for Dal-hee, the main character of ‘The Postman from the Underworld, Baedal-hee.’
Dal-hee, a fourteen-year-old who has just started middle school, is too shy to say no even in situations where she thinks something is wrong.
One day, a grim reaper visits Dal-hee and gives her the task of delivering the last letter from the dead.
Dal-hee, who accidentally became the world's only postman in the afterlife, takes a special elevator every night to the afterlife and delivers letters from the dead.
Se-hee, a visually impaired girl who blames herself for never properly playing with her guide dog Haru who was always by her side; Min-jae who regrets not being able to say thank you to his mother who worked late to pay for his expensive private academy; and Ji-woo, a friend who is saddened by the passing of his grandfather while he was only concerned about his grades.
As she watches those who received the letters overcome their regrets and longings, Dal-hee also gradually realizes that the moment when she can honestly express her feelings will never come again.

Whispering to those who hesitate to approach,
The courage to tell your true feelings without regrets
“There is a feeling that I can only reach now.”

The main character Dal-hee's biggest regret is 'not being able to say hello to her distant friend.'
Dal-hee, who became estranged from her best friend last year for no reason, finds it difficult to approach new friends even after entering middle school, and even when she runs into her close friends on the street, she hides without saying hello.
Dal-hee's appearance, which causes her to drift apart from her friends due to a change in environment, reflects the concerns of teenagers who feel confused about their relationships with friends.
Whether it's the experience of a friend you once did everything with suddenly becoming difficult to even talk to, or the experience of remaining distant because you were too shy to express your feelings to a friend you were interested in, any teenager who is still awkward at forming relationships will likely harbor regrets about not doing their best for the person by their side.
Through the process of Dal-hee, who resembles that figure, growing up, the work instills in us the courage to reach out first to those we want to become close to, and the confidence to confidently express our true feelings when absolutely necessary.
In addition, it gives us the strength to share our true feelings that we have not been able to express to our friends, family, and others around us through the stories of the deceased who passed away suddenly and the recovery process of those who remain in this world.
"The Postman from the Underworld, Bae Dal-hee" is a healing fantasy coming-of-age novel that will give young readers who hesitate to approach someone the courage to convey their true feelings without regret.
Just as Dal-hee delivered a letter across the worlds of this world and the next, I hope this work will provide an opportunity for everyone who wants to say something they have never said before to do so.
