Escape from Japan

Reading the Heart-Wrenching Sadistic Novel, I Was Heartbroken for the Characters in the Novel.

I want to read a book like "Honey, We've Divorced". There was a divorce at the beginning, and the male protagonist was so devastated. They promised not to separate, and promised to be together forever. These vows were vulnerable to sudden changes. The family suddenly suffered a major change, and the family was deeply troubled.
