My wife left home, so I went to my mother-in-law... Reiko

it's been seven years since i got married... Keiichiro does not give birth to children, and lives a different life from the truth of his wife due to busy work. One day, Truo suddenly ran away from home. It was Keiichiro, who thought of Truth A and visited his stepmother, Ririko. However, even if Ririko asked him, he couldn't find out where Reshia was, and Keiichiro blamed himself for 'why didn't he get more involved?' Seeing such a righteous son, Ririko can no longer look away from the fact that her daughter is suffering from Keiichiro.
