Ootsuki Masami

There are issues in her marriage due to differences. She went to her husband's parents house to make him worry about her a little.

She does not show any attitude toward the protagonist, her father-in-law, but she even dislikes him because he is crass and has a lecherous look on his face.

However, sexually, she is a strong M-oriented woman who likes to be pushed around and overwhelmed by momentum.
