Otto wo Konoyo Kara Kesou to Kimemashita

Overview

Asami is under constant stress from her narcissistic and complaining husband. One day, Asami finds a hotel receipt and contraception in her husband's wallet. Instead of questioning her husband, Asami tries to get more evidence. Later, she witnesses her husband having dinner with another woman at a hotel and then staying there... Asami thinks, "I wish that man would just die," and struggles to erase her husband from this world as soon as possible. (Source: Natalie, translated)
