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 she 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.
