I am a college student who wants to be a novelist. I used to go to a coffee shop called Northern as a place to write and study. He says "quiet and calm", but in reality he is in love with his master's wife, Nao. Every day I can't write or study because she's fascinated by her bewitching atmosphere. One day, when I visited Northern on a regular holiday because I misplaced the manuscript, I witnessed Nao who was forced to play metamorphosis by her husband.
