Rui (Ayukawa Rui) is worried that her husband's stepchild cannot open up to her. She wants to build a good parent-child relationship at any cost, so she decides to take hard-line measures. It was a strategy to break into the bath where her son-in-law was bathing and try to close the distance by naked socializing. If this is the case, Rui rushes into the bath naked, saying that she can open up to her son-in-law. This action becomes the trigger to explode her emotions that the son-in-law has been hiding.
