[Reducing Mosaic]DKTM-020 Two mothers!!! My mom and stepmom are having such a hell of a time, I'm at my wits' end!!

A story of a certain boy. A few years ago, his mother and father divorced because of his father's affair. Then I got a new mother. I wonder if she is what is commonly called a mother-in-law. So I have two mothers. Her real mother, Izumi Terasaki, who gave birth to me and raised me so far. Her stepmother, Kaori Otonashi, treats her kindly even though she is not related to her by blood. Apart from my father Tatsuo, I can live under one roof with two important people. I thought I was just waiting for a happy life...
