Yoko Narumi is Sayuri's younger sister. Sayuri was divorced 20 years ago and now lives with her only son, Kenichi. Yoko comes to her sister's house as soon as something happens because her house is close to her sister. Today as well, my husband's cheating was found out and it turned into a big fight. Kenichi was the only one at home, and he pounced on Kenichi as if he hadn't cheated on him because his husband had cheated on him.
