100-nichigo ni Otto wo Suteru Tsuma no Hanashi

He controls her! He criticizes her cooking! He denies her affection and belittles her! Yuuka is a full-time housewife whose husband is piece of trash. She was already fed up with his emotional abuse, but her husband is also having an affair! He seems to be trying to hide it well, but his new girlfriend, a modern woman, is posting hints on social media. However, contrary to her husband's expectations, who thinks Yuuka is a "naive and dull woman," Yuuka and his girlfriend are from the same generation! Digital natives! In other words, evidence is piling up. In order to live happily with her daughter, she must not take the easy way out by "just getting a divorce without any preparation," but must take revenge and squeeze out child support and alimony!!!
