The 'Oshima' who ended up living with his son's family in Tokyo. But the wife of his son, 'Shumi,' is cold and always has a sour face, so Oshima has long disliked her. One day, 'Tetsugaku' gets injured and ends up hospitalized. "Oshima" tried a cruel joke on "Sumire" in their awkward life together, saying, "Our son died at the hospital..." Sumire, who was usually expressionless, showed an unbelievable shocked face with her eyes about to pop out. "Oshima" was surprised by that expression and later wanted to see "Sumire's" funny faces, so he started playing pranks on her, but she remained stone-faced. Then "Oshima" finally resorted to suspicious drugs... #YoroP
