JUY-421 Madonna debuts!! Son's wife Maria Aizawa

Maria worries about her husband who lost his job due to gambling addiction. She asks her father-in-law, Ginji, to help her get back on her feet somehow, and she starts living with two households. Maria almost loses her self-confidence because of her husband's stubbornness as she refuses to change. However, she is saved by Ginji's kindness, and she begins to feel more than a parent-child relationship for him. The relationship between the two who have crossed the line is rapidly approaching, and the act escalates day by day.
