While struggling with her marital issues, Hikari begins caring for her father-in-law, Eiji. Unlike Takeshi, Eiji treats her with kindness and warmth, gradually capturing her heart. However, after accidentally discovering a shocking side of Eiji's true nature, Hikari develops intense feelings for him. She straddles Eiji as he sits in his wheelchair, passionately kissing him deeply and intensely. In that moment, driven by both love and desire, Hikari shamelessly grinds her hips while tightly pressing her body against his chest.
