That's where you can read somebody else's notebooks and diaries. A designer shares the record of his life, a high-school boy wrote down his one-sided love, a college girl pours her mind out on a notebook... What you find there are inner thoughts of everyday people who live the same era with us. What do contributors of the notebooks have in mind? What do those who come to read them wish to find? Hidden thoughts and feelings come across each other via 400 diaries that were never meant to be read by others.
