A student transfers to a rural school to receive treatment for his atopic dermatitis. While repairing his new home, he discovers an old red-patterned box and worn leather shoes in a small room where the roof has collapsed.

Upon opening the box with his classmate, they find a diary, a book of poems, and a Pinocchio doll, realizing that the owner was a girl who died at the age of 17 while living in the abandoned house. As they uncover the mystery behind the girl's life, they also help a fellow student, who has been bullied.

This is the physical copy of the Red Patterned Box novel.
