This book combines magazine and calendar. It shows human's emotional reaction to a heartache and the process of recovery back to normal. Each page marked with mathematic, ancient symbols and other symbols from different frontiers represent a phase of feeling. Three types of paper symbolize the process of recovery from heartache. First part begins with Japanese paper with a rough texture which expresses the heartache's initial stage: humans pretend everything is good, even when the truth is that they feel sad. This phase is followed by the thinnest paper in the second part. And for the final part, I chose a strong paper with smooth surfacing, meaning humans restore mental equilibrium.
